Let me clarify a bit:

The nut is already reproduced. The gasket is already reproduced. My adapter can easily be fixed (fill the pits with zinc and replate) and my local chromer can do that for me.

All of that having been said, this part (the adapter) is not being reproduced as far as I know. I don't mind holding 50-100, depending upon cost, of course, and selling them out over the next 10 years (or more).

Surely, my immediate problem is solvable as my adapter is structurally sound (not rotted through anywhere). I was thinking of the bigger picture and from there, perhaps other small, rarely seen parts.

Now, if I could do with only having 10-20 made, that would be even better, I 'spose.
