Can you ID this Receiver? Grayson Finds a Homebrew Receiver in Germany. From the GDR. Circuit? Schematic? Thermatrons?

 
Grayson Evans KJ7UM (the author of  Hollow State Design) was recently in Germany where he spotted this museum display of a homebrew receiver built in the GDR (the old East Germany) around 1983 by a 13 year-old.   Very cool. 

Here is today's task for SolderSmoke:  Can you provide any more info on this receiver? The card indicates 0-V-1 which would be a regen with no RF amplifier, right?  Maybe something like this: 

 Look carefully at the pictures and try to gather any additional information on the receiver or its builder.  






Thanks Grayson!

    I'm thinking the valves are Soviet made 6j1p.

    I thought this was interesting.

    The builder would be 53 now. I don't see how the tuning would work.
