Keith,

Thanks for the very interesting, very detailed information on the
history of Addressograph and the plates for the machines. I've
been surprised at how thoroughly information on these machines seems
to have disappeared - moreso than in other areas of old technology.

What would a "suitable metal" be? Stainless like the dogtags?
Or a softer metal such as brass or aluminum?
Is the (approximate, even) metallurgical composition of Alloy B known?
I tend to like to preserve consumables when the get to the state of
rarity that they're collector's items, so I'd like to figure out
how to make my own plates (without damaging the machine - I did
note the WARNING not in the "Reference Book" not to run it without
plates).

Thanks again for the information!

David M. MacMillan
