Clean inside, staggering amount of trimmers, counted to 46-47 powers up, beeps, crackles and burps a bit, but after settling down some signals.
Edit: found schemo for 4010, 4020 4021 4022 quite straight forward machine, i save the 10Mhz ovenized crystal reference and junk the rest.

Keep those decade switches, they are quite useful at times, especially make sure to use a wire to keep the whole assembly with the end pieces and spacers together. They can be BCD, reverse BCD or even 1 of 10 selection depending on the model. Quite useful at times to do selection of data or for selecting data that can change occasionally.

The rotary switches and pots on the front may be worth keeping as well.

I'd try to get it working as well, you could build a complete radio service bench around an instrument like that and it seems a shame to scrap it.

Oh that's a real shame, it'd be a great piece of kit if you were into radio repair, servicing or homebrew.

I'd have been very interested in buying it as faulty if you were in the UK
