As already mentioned, you could source one from Amazon. Likely your best bet. In looks and function, it appears fairly similar to the the 1880's vintage crimper tiriaq likely uses. I have one (1880's vintage), too. Use it regularly. Clamps onto a bench or table top. Easy to use. Produces a consistent crimp.

Lyman used to make a roll crimper that attached to either a drill press, or power drill. Not sure whether these are still available, but may be worth a look. I have one....works very well. Best used on a drill press. Where the depth of the crimp can be easily controlled.
