Interesting hammer on the Beals. The spur curves forwrds, the rearward at the tip. I think someone curled over the Spur so as not to hang up or so you could cock it easier. Cool!
Here's a few of mine, two remy's and a Rogers & Spencer. All three conversions. Both Remy's are 44 Rem/Colt 44 C.F. and the R & S is 44 Hemry Rim Fire.
