Thanks for the beauty background info Ralf!
There was likely an arrangement between Record and Dawn, and maybe a loose one at that.
I have a small Record vice out in the shed that I refurbished years back, a 0 or 00? that is made in Australia. I have never seen one before, or never noticed

I was going to list it until I saw the 'Australia' cast on the body.
The Joplin looks like a go to own and I would jump at an early one. Nicely engineered!
I see that there are vices marketed as Joplin still being sold but they don't appear to be a patch on the old ones' for weld finish. The Dawn that I have is also the same in respect to the weld, very consistent as opposed to what I see on the current new examples up for sale. And the screw is a serious size too.
Would I be correct that Dawn adopted the Joplin style tag when they took them over? The modern ones have the stamped 'Dawn' and a transfer; tacky Asian style.
I am still waiting for a reply from the sheila at Dawn but I don't hold out much hope; it was a bit of a good natured poke in the ribs anyway.
All the best to you Ralf, cheers.
