Actually I got it from Udo Radke, german collector, his (homemade)design...I wish I had one from TFK or IEE..
I asked in the past for some good photos of that board too... it would be nice to replicate it

Is it a home-built testing unit or something that Telefunke/IEE designed?

I had a look at some photos Robert sent me and found that the circuit board consists of two (2) Fairchild 9112(59) "High Voltage Hex Inverter", one Fairchild 9301(59) "MSI 1 of 10 Decoder" and the SN7475N "4-BIT BISTABLE LATCHES" and some resistors and possibly a 5.1V Zener to supply the SN7475N and Fairchild 9301 with 5V as the two 9112 uses somewhere between 12-20V to interface to the NIMO.

I have a testing module for the xm1000 
If you " throw it" across Atlantic , I might be able to test it for you  ☺️
