Is there a book or reference (internet site) that someone has put together on non antique (say post WWII) builders and manufacturers of muzzleloaders? I ask as I come across rifles, on GB or Armslist or in person, and I nor the seller have any idea who made what looks to be a good quality rifle, or maybe a decent factory gun that is not an import. For example, I have using this forum and google sort of gleamed an understanding of who Bill Large was, I think I understand Austin & Halleck, and the CVA/Deer Creek line, and then a new name/maker will pop up - any handy reference out there? Thanks
