Don't get me started on Mosins LOL, I've several 1891/30s (long-uns) which I admit I have a "thing" for, you could collect an example of each though for not much money! I still need a 1944 carbine but I keep buying 91/30s instead whenever I get to an event.
The Birmingham motorcycle museum fair this sunday should have some good mosins! in the meantime have a look at this website for more info on them
Cheers and good luck
