Rarest thread gauge?

[Braeden P]

So last year we were cleaning out my great grandfathers house and I found this thread gauge. I can not find anything on them and only one that is for sale I have been searching for months and finally found one for sale but that only makes two, so do any of you guys have one or a athol machine co catalog? I believe that it is from 1880 to 1910

That's one of the companies that Starrett Precision Tools bought up in the late 1800's. My guess is that this gauge is identical to a Starrett gauge of the same period.
