Hey swa,

Welcome to the TNet. It might be useful to know the dimensions of this piece, and from what instrument company it was produced.

It's post 1963. Cool looking hunk of steampunkery, to my eyes.

I sell a lot of things I dig up (copper especially...pipe fittings - old gears -keys) to someone who makes steampunk stuff - they really enjoy the stuff Ive dug that has turned green (though some people go for the "everything polished" sort of look)
