What is this doing in my collection?

What is the 'odd ball' artifact in your militaria collection? I am thinking of that something we picked up which doesn't quite fit the norm in our collections (a bit like this thread ) but at least has a militaria connection?

These are my top two oddities:

1] A mint condition German transmitter pentode dating from 1944 (in Warsaw). The glass tube is 48 mm dia. and 145 mm height (not including the pins). Well it does have a Polish connection

2] Soviet nuclear bomb radiation blast/fallout calculator from 1967... well you never know when it might come in handy—cold war or no cold war I'm still looking to the East

Well if it does happen you could always use the pentode to let everyone know!!
