There are a few of these Thompson Center anniversary Hawken rifles out there for sale now on gunbroker, I don't recall one being made in .54, only .45 and .50 cal 15/16th inch barrels. If value is what you are looking for, The best way to determine actual value is to search the on-line auctions, such as www.gunbroker.com and www.auctionarms.com or even www.proxibid.com enter your details in the search and see what has SOLD and for how much. if there is nothing current try the archives of past sales or items sold. Another place to look is The blue book of modern black powder values available from www.midwayusa.com Don't forget condition has allot to do with value, so compare apples to apples.

Depends on the Thompson. If you mean the Thompson submachine gun, yes, they were made in caliber .45 ACP (and other calibers as well). However, there are other Thompsons. I have a Thompson Center muzzleloading rifle that is .50 caliber.
