Badge "Excellent Military-Naval Constructor".

[Chris]

This is the modern 1970 issue badge that was a meant to be a reissue of an earlier badge but was rejected.

I am going by Avers 1 description, which says that it made this badge in small numbers and rejected it.

Mine matches Avers 1 description.

The newer version 1970

The modern version is longer and the older shorter

This is the gist of the Russia in my translation:

This is a test example and very few were made. After production they did not like the results and stopped it.

Collectors who have this badge think its worth a lot but in reality it is worth little as there is no demand for it, as its existence is not generally known.
