[Sneap] tungsten mesh sought for gridded einzel

[Klaus Bahner]

Albert,

We purchased our tungsten mesh from

UNIQUE Wire Weaving Co, Inc
762 Ramsey Avenue
Hillside, New Jersey 07205-1094

I took the address from the shipping box, but I don't know whether they
still exist neither do I know whether the can supply electroformed tungsten
mesh.

Hope that helps,
Klaus
