This is not a classified ad. So please don't treat it as such. However ... I've got a couple of WW1 collectibles. I really need to add a correct M97 trench gun to the list. I've googled my brains out. I've been watching gunbroker for months. Can one of your shotgun collectors point me towards a place to start searching and looking? I passed up on a very nice and correct M97 10 years ago for $500. Boy those were the days. I fully understand what a nice one will cost me. I just need ideas on where to start searching. Thanks for any advice.
