This is the best gunmaker's vise I've ever seen. It belongs to Al Lind in Washington. ...

Great design, thanks for sharing-maybe it'll inspire a home-machinist to make a few and test the market. Unless of course we can find a ready-made one!
edit: 15 minutes later and I've just looked through about 1,000 used vises with zero luck. Maybe it's European? or a one-off? Somebuddy ask Mr. Lind please. Thanks.
