Picked this one up along with some other gun stuff at a garage sale on Sunday. Didn't actually know what it was (Luger's aren't in my knowledge base). But it looked cool though, so I figured if all else fails it'd make a great prop for a comic-con outfit.
Did some Googling tonight and it looks like these things are worth a little.
As far as I can tell from the info on Google, it is a First Issue, with telescoping thingy (not the ratcheting thingy). It's a Bing Brothers. Serial is in the 53XXX range. Finish is worn on the raised surfaces and corners a fair bit.
How do I figure out if it's in good working order and not broken? I'm not going to try to load a century old drum with a handle on it unless someone tells me how.
What's a good guess at its value, or where can I determine it's value? Condition is difficult for me to assess on something this old.
