The “Lunacharsky” N 402-II-72 was purchased on eBay in the fall of 2014. When I originally saw it I thought it might be another of the Moscow Experimental Factory instruments. But this instrument was actually built in 1972 at the Lunacharsky Factory in Leningrad (now Saint Petersburg). It bears a strikingly similar resemblance to the Moscow Experimental Factory instrument, which was the original impetus for this site.
This first series of photos shows the instrument in the condition in which it was received. The condition overall was really good, and it only needs some cosmetic “fix-up”. There were a lot of nicks and divots that need to be filled, especially along the edges. Luckily I was recently gifted a Behlen Burn-In Kit, with all the waxes/fillers and the iron I need to fill these nicks.
See the technical specifications and measurements sheet for details about this specific Lunacharsky instrument.
