It shows 1902 stamped into it, but I think that's just the patent date, so not sure how old it might be. From what I've gathered the company quit making things in the late 1930s, so it's still pretty old either way.

Cleaned it up a bit tonight and unfortunately, it is in dire need of a honing. Was hoping a little CrOx would fix it up enough to try out, but no such luck. I really need to get my own hones one of these days, but it looks like for now ill have to send it out before trying it.
