Did you rebuild the diaphraghm on the Ultona?

I personally did not, but it was rebuilt yes.

Are the discs' solid shellac or do they have a core of some other materila?

According to Ron Dethlefson, the expert on Edison discs, Diamond Disc cores were made from finely ground wood flour (not coarse sawdust, as some have speculated) together with an asphaltic binder. In 1921 the core or "powder blank" composition was changed to include china clay and lesser amounts of wood flour. This was done because it was found that wood flour absorbed moisture readily whereas china clay did not. The china clay cores did provide protection from moisture.

When I think of all the old records which my parents and the rest of us threw out in the 1950s.We considered them to be "old-fashioned" and no longer of interest.I could weep!

Just love that song, can you post the entire song?

I think that Brunswick is totally awesome. I always wanted the Brunswick 117 tabletop with Ultona Reproducer, I think they play the Edison DD's just as good as the Edison machines. I always wondered, do they use the same stylus and bar as Edison DD Machines?
