Original Wiedmann ISA. Stewy
Give it a Vaseline bath, as it looks like it may have the on set of zinc pest. It's been badly stored, but it's hardware set up is not rare. But not always encountered. Stewy
Out of interest, if you have a magnet handy check the pin. It looks rusty. Stewy
If you do a search there should be a thread on how to arrest zinc pest with Vaseline treatment. Stewy
Just don't use Anusol, that's different.......
'I do not think we can hope for any better thing now.
We shall stick it out to the end, but we are getting weaker of course, and the end cannot be far.
It seems a pity, but I do not think I can write more. R. SCOTT.

As Stewy stated, this one is a good E. Ferd Wiedmann, Frankfurt am Main ISA.
The hardware set up is a barrel hinge and flat stock catch.
This particular variant is one of the rarest of the solid zinc Wiedmann examples.
If you do decide to use Vaseline, does so sparingly and apply a light film after you clean the surface.
Here is one I have to compare.
