This one I picked up last week. It looks to me to be a Haynes Griffin. This super is well built and compact.

When I was new to radio collecting back in the early 90s I would see Billy Richardson's fabulous creations in Texas shows in Houston and Dallas. I was always blown away by the workmanship and folks had to inform me these were modern creations by Billy. I have always been a big fan and I always considered them art made by a true artisan. So when I had a chance to get one of Billy's radios after his passing I pulled the trigger. I'm the current caretaker of Billy's Madison-Moore set. Its based off of the ealrly coils (before one-spot) and Madison-More audios. Is it a recreation of a period set or something completely out of Billy's mind? I don't know and it doesn't really matter to me, its just a fantastic set that i'm incapable of taking good pictures of :). I removed the "c cells" Billy installed in 1995 which I can only assume that this is when he completed it. I'm undecided if I should polish all the chrome and nickel or continue to let it age. I suspect maybe Billy would have wanted it to eventually fade into looking more aged considering he used 'aged Laquer" in the lettering instead of bright white.

I want to get a loop to go with it but really it should be a reproduction loop :)

From my understanding the sets in the below picture have been placed in collections/museums in different places. It was impressive seeing them all together, i can attest.

Just... WOW! :shock: :D

Reproduction or not, that is just stunning. I'm drooling. :wink:

I witnessed the results of his awesome craftsmanship at the AWA Conferences in NY. But as an amateur historian, his creations always left me uneasy. He apparently drew perverse delight in never coming out directly in saying what was 'legit' and what was from his fertile mind. i.e. Some of his 'supporting bogus documents'. What I surely hope is that the provenance of these creations is never separated from the artifacts. There should be museum grade catalog tags attached permanently. And yes, properly identified, I'd love to have one of his creations in my collection.

Was it meant to look like a new radio that might have been sold in the 20's in like new condition?

If so then definitely polish it.

If not then don't.

Congratulations on acquiring one of the best that Billy produced! It is a great looking set. I would let it age gracefully.

I guess at some point he got the message. This one has a "Richardson Radio" tag inside it.

Picked this small booklet at the June MAARC meet.

Nice find David. Does it have a date anywhere on it?

Ever noticed how so many of the 20s battery superhets have a panel meter (or meters)? It seems like they have them far more frequently than other types of sets from that era.

Why would that be? Homebrewers just wanting to make their sets as well-equipped as possible? Or is there a technical reason?

2 reasons I can think of off the top of my head.

1. Most suerhets were kits and thier designers/builders were not as budget minded in the construction of thier sets as were so many of the big volume radio manufacturers were such as Atwater Kent, Freshman, and Crosley.

2. When your powering up between 8 to 10 very expensive tubes, you'll want some sort of confident monitoring of their filament voltages.

Eight to ten tubes puts a heavier drain on the batteries compared to a radio with five or less tubes. Superhets were also more complex than most TRFs. A combination of those things, and possibly more, made it desirable to monitor the battery conditions with a meter.

Great answers, and they make perfect sense - thanks!

Another one for me. Seems to match the one referenced on Duane's excellent site, http://www.duanesradios.info/html/all_american_if_transformer.html.

The layout is a bit different from the magazine article but uses all the All-American parts and 2 Columbia 2:1 audio transformers (both bad). Someone in the far past installed a coupler (R-140) for an external antenna, which arrived removed. It tested bad on one winding, however a replacement R-140 coil and a good transformer came with the radio :D .
Remler butterfly tuners. Socket on the left front is for a loop, 2 stages of audio on the right. Some kind of key needed for the on/off switch (anybody have one?).

Cool super. The owner probably had a bunch of kids running around the place. These are the only two I have found. Yours looks sort of like the cutler-hammer filament switch. ref. June 1925 Radio News.

A better picture of the C-H Radioloc key. Oct 1925 Radio News
Maybe a broken off knife switch?

This summer I purchased this Tyrman Imperial 80 for $10 in an auction. It had belonged to Dale Davenport and had been shared on this thread long ago. Norman had made a reproduction capacitor pack which mounts to the back of the chassis for Dale. Norman told me that he had the pack and he gifted it to me. Thank you again Norman.

My understanding is that the 80 Imperial is not very common, and it is identified by the wood front panel, which is actually wood bonded to a metal plate, and the phono switch. This radio has plug in coils and can tune the short wave bands. The radio had a hack job done to the condenser shield to make it easier to switch coils, and I will need to search for the impossible to find missing tube shields.

I just acquired a 1920s superhet. It sort of fell into my lap. I haven't much experience with 20s battery radios. The closest I've gotten is a Radiola 18, obviously not battery operated, but 1920s.

When I got this radio I had no idea that it was a superhet, I figured that a 20s radio would likely be a TRF. it wasn't till I got it home and started to examine it that it became obvious to me that it wasn't a TRF, and was in fact a superhet. I started looking on the web and found Duane Bylund's site. Looking around his site I found that my new radio is very similar to the one shown on his Leutz C-7 page. The front panel is almost identical except that it has three filament rheostats instead of two.

When I first got it home I realized that I needed to develop a schematic diagram in order to figure out what I had. What I came up with matched the schematic for the C-7 shown on Duane's page, and the photographs looked very similar to mine, except that the IF transformers looked quite different. The transformers in mine look like small tin cans painted gloss black, with a small oval label on the side that reads "radio frequency transformer" around the edge of the oval and "Model C1" in the center, no manufacturer's name.

The set is missing the bias battery for the audio tubes, but the first detector bias batteries are still in place, expiration date June 1930. I measured about 1.8 volts across the two, not bad after almost 90 years.

It came with a full set of tubes, five UV201As and two UX201As. One of the UVs is a brass-based one with a top evacuation tip. So far I've only checked the filaments, one of the UXs has an open filament, the others all have good filaments. I have a few UX201As in my stash if I need them.

All of the transformers and coils check good for continuity.

The radio is in very nice condition and is pretty clean. I'll probably just do the minimum I need to before I try it.

Here are a couple of photos. The second audio tube was out of its socket when I took the photo.

Basically what you have there a Leutz C-7. The lower potentiometer knob, between the two meters, looks to be an add on as with the upper speaker jack.
