I just came across this Am/FM Tube Tuner that I bought years ago and have no idea the make or model.
there is no id anywhere except some numbers on circuit board and metal chassis that I'm hoping somebody
will recognize. I am supplying pics that might help.

The circuit board has lettering PCom2264a and also Harman-Kardon 1956 but I figured that doesn't
mean that it's a Harman Kardon
Chassis has 1800346

Tubes are: (2) ECC85, (2) 6au6, (1) 6be6, (1) 6al5, and (1) 6ba6
All the Tubes are original and Imprinted with Columbia phonograph, Amperex, Holland

The tuner works great but it would be nice to know the manufacturer
Thanks for any info

Would be easier if it had a front panel - The top cover suggests it DIDN'T come from a console though. This would have been a lower-end tuner if it was sold as H-K - they also private labeled for Radio Shack early on, and also for Steelman and EJ Korvettes, likely others. The tubes and control layout match up with the H-K model T-12 tuner from about 1958 - power transformer part number is FT781419 - if that matches you have an ID. https://www.radiomuseum.org/r/harman_t_12.html

The copper-plated steel chassis was typical of H-K in the mid-late '50s. My guess is if an actual H-K, it's a model A-300 Theme, 1955, T-1040 Theme II '57/8, T-120 Rondo, '57/8 or T-12 Overture II '57-58. After that they looked quite different.

It sure looks like an HK to me. I’m quite certain I’ve had that tuner in it’s complete form.
I’ll check my Manual file to see if I can identity it as to model # and scan the manual for you if I do indeed have it.
