A good Broomhandle forum?

[Jim Mac]

Just picked up a broomhandle mauser today. The broomhandle and P08 has been two guns on my bucket list. With all the panic buying for assault rifles out there. I posted a wasr10 ak that I picked up in trade a few years ago. What I got was a mixmatched C96. the lower reciever is in the 11XXX range the upper is 508xxx range on the serial numbers. The rest of the numbers dont match each other or the frames. the hammer doesnt have the NS and its got a importers stamp IA CO SAC CA
The I could be a T and on the other side it has its got germany stamped on it (right side) with 7.63 stamped in real small numbers. Its pretty obvious its been reblued and polished before. I did read up on checking the bolt stop and it looks to be fine. The barrel has been bored out to 9mm and since I dont have anything to check the diameter. I did the bullet test by sticking a 9mm in the end of the barrel and it doesnt go all the way in. I know thats not the correct way to check but at least the bullet didnt completely fall into the barrel.
So is there a decent mauser forum like this for lugers?
Any infomation is appreciated. Happy new years. jim
