An interesting website that I found easily kept me occupied for an entire morning with the range of topics it covers. It's a blog devoted to WW2 equipment that continued in military use after the war but also has a few items of Cold War era equipment being highlighted due to some interesting facet or other.
For example, there's this image from the page titled
Urgent Fury 1983: WWII weapons encountered, I'm sure people here can find a use for it

Main page for the blog is here

There are numerous tags to make searching a little easier and I found it holds a lot of images that can fit into the T2k theme, like the following image of Austrian tanks.
Rearming Austria: WWII weapons
