Oliver also made them and I have seen one (an Oliver) on
eBay recently. I could be wrong but I believe the Olivers
might have been the very earliest (original?) patternmaker's
All my older Kindt-Collins (still in business) catalogs list
Emmerts. My '87 catalog shows essentially the same vise
branded Kindt Collins.
Your "go to" guy on this subject is Jeff McVey. I'm pretty
sure a search of Al Gore's Google will bring something up on
him. If you have difficulty ping me on the back channel and
I'll fish up his e-mail addy. Anyway, he should be able to
spew off any vise makers we haven't touched on so far and he
may be able to shed a little light on availability.
Oh, and your original question, makes a good point. Aliens?
Personally, I think there's such a market for any
patternmaker's vise that anything that comes on the market
is snatched up right away (its feet never touch the ground).
