1005 is a chassis used in a number of different models of varying values. Most commonly seen in the 10S464 console with a value of roughly $100 or so in low average condition. The 10S452 chairside and the 10S443 table set maybe more like $300 and the very stylish 10S470 console maybe $600. Also two radio-phono consoles, 491 and 492.
