HI everyone. I ran a 8000lb double action erie steam hammer for 30 yrs. I've seen a lot old hammers. A lot from the 1800's. I now volunteer at my communities heritage village as s blacksmith. I've personally used a few of those knucklebuster hammers. Now I'm looking for a few different style hammers for forging museum we have at the village. The 3 I would like find are a helve hammer(think I found one), a chambersburg 300lb hammer, and most important to me personally,Because it was Canadian made, is any size "Lil Giant" or "Moyer" hammer. Think theres only a 25lb, 50lb, and 100lb. Configuration. Any help or direction in the right way would be greatly appreciated. Thanks yall. If I can answer questions about forging or running hammer for anyone...Feel free to ask I'll do my best to answer you... Peace
