Not sure but looks like a simplified valve tester. For sure Yuri will know.

have a look at this one:

This does look like some home-made tube tester. I see some familiar sockets in this device.

Looks like a home made device. There are a few Wehrmacht type valve sockets, but the majority are civilian types. It lacks an indicator instrument to measure the currents through the valve which I would expect on a valve tester, so it is probably a valve regenerator.

yeah I know that there is not serial product, but I think that is made from German devices.

Here is another picture.

thank you all for help!

There is a good way of checking if components come from German miliatry equipment. Normally components have a component number on them. This helps to trace the component in the schematics. The component numbers are ususally ink stamped or they can be small oval transfers. So on resistors you usually find R1, R2 etc, on capacitors C1, C2, etc, on Switches S1, S2, etc. etc.
