Crikey! do they still make that? When I was a kid it was promoted in
kids comics and the 'Railwaymodeller' for making models, it came in
tins with press on lids - that takes me back.


Heh, they still make Wood's Metal also. I have some radio books dating
back to the early 1900's talking about setting galena in Wood's Metal
as not to ruin the crystal.

Thanks to the magic of the Internet, nearly everything is available!
