I just came back from a long road trip where I hit every antique shop along my route.
Warning: Being a Fallout fan, and going antique shopping is a dangerous mix. I wanted to buy everything even remotely close to a Fallout prop!
You have no idea how many radios, fans, toolboxes, luggage, and other things I had to pass on just because I wasn't quite accurate, or way too expensive.
I scored lots of goodies. I may be using the large green case for the Pip-Boy build. It was very hard to find cases with all-rounded corners.
--------------------------
my best find of course is a injector and gauge for a future Stimpak build.
--------------------------
I got both parts in the most amazing antique store I ever have seen: D&J's in Brady, Texas. I mean with a display like that in their store, you know they have some dark Fallout humor in their bones.
------------------
/Edit: Double score!
I just figured out that the random piece of cool looking electronics I bought is actually a Victoreen Radiation Survey Meter (Geiger Counter)
It is similar to this one, but so far I haven't found an exact match.
