@okgb Thanks for the compliment on the photos. I'm definitely not here just to sell things. I have built stuff too like mnats fine boards, serpent audio, etc. I just have less time for DIY and need to get rid of some stuff.
@mutterd small world! I don't know if these are officially military-rated, but I know for a fact they were being used in US military builds in the up until at least the 1990s so that says something about the durability.
