If has to be a modern heuer front, I'd try to get an older used one where the screw is still in a tube and maybe even the visible nut. Looks so much cooler IMHO. The pre war model is completely different with the round bar. Still lovely (all are hard to get in my part of the country, though. But I see that one 150 mm pre war one sitting there for 60€ "shipping possible". And I do have a Primus DRP 150mm just sitting around, too.)
On a side node, I was able to talk the owner of that VS2 near frankfurt into shipping it to me, I luckily got a fitting super sturdy DELL box (why did I throw its sibling away 6 months ago? Why?) at work, and some heavy duty styrofoam, too. So of it goes for 6 Euro, he gotta put it in (I had that template to work with

. And back it comes. I put some bribe in (Stollen cake, it's

soon, isn't it?). If everything is good, then the new vise just needs some JB weld to fix some cosmetic problems (they are not compatible, new vise is thick jaw insert, old vise is thin jaw insert with thicker cast to make up the part that used to be insert).
Which also means that if everything turns out fine, a VS2 can become your vise. Because I have the perfect shipping box already prepared. (If I keep this box I might want to sweet talk other sellers into the same deal, better not). Be warned, though, this vise needs some reconstruction work to recreate the anvil plate, so unless a fake anvil will do, you might want to be able to machine or bend or weld metal together into a u shape and braze it on (Well that's what I'd try to do).
