I managed to find the time and just recently started to work on the restoration of a number of old â€œoriginalâ€

How does one repair the rim pit and abrasions without altering the original contour of the rim?

In the case of this sort of paperweights, where there is no original contour, the outside of the mouthpiece is planished (sp) or hammered using specially shaped tooling. The rim is then re-cut on an engine lathe to as close a dimension as possible (using an original mouthpiece as a guide). I use fixtures I constructed, to hold the part properly on the lathe without the risk of damaging it. Normally, on a better mouthpiece, the rime is lightly worked, wet-sanded and then burnished prior to polishing and plate. But when there is little to work with, you push as much metal as you are able back in place and re-sculpt. Its not real difficult but one does need to be careful and take there time to avoid the removal of so much metal that there is nothing left to work with. Silver brazing the bad gouges helps fill them in and again, helps one avoid removing more metal then needed. No, they are not perfect but if you take the time, it is possible to get them in reasonably respectable condition but not always.

I'm the seller of the mouthpiece, and I'm glad it's in good hands and that it made it to the restoration shop. I play tuba only occasionally, and on a smaller mouthpiece and an inexpensive, non-vintage tuba, so this mouthpiece was not worth restoring or keeping for me.
My dad got it at a flea market, probably for $5 or less.
How does it play?

I hate loose ends, so I thought it best to share a few images of the completed mouthpiece.

If it is indeed Horn-PornÂ®, where those with a vintage Hellberg fetish are concerned, these are no doubt the center fold.

Yes, they are all real, pre-war Conn.

I see several... Does that mean you're producing them for sale?If that's the case, how much would one of those put me back?

Sorry if I got you excited, these are all recently completed restoration jobs for a number of my clients. They are difficult to find and value is quite high due to there demand.
