Hi Heiko,
Seems you've drawn a blank so far on here with this.
I'd be sending a PM if PMs accepted pictures (you don't show an email address in your profile) so here we go . . .
I don't know if what's in the picture would help / suit?
It's a reasonably decent one. Missing the big dished washer and the horseshoe washer, but the left hand thread still works (for how long? who knows!?) and the movement and springs seem smooth and correct. I haven't opened it up to examine the mechanism for wear on the inside, but there's nothing obviously 'bad'. A new fibre pinion is lying around too if you wanted - the one on it isn't bad to look at, but as you know they don't last for ever and are a pain when they shed teeth.
If it would be of any use, let me know. It also has the advantage of already being in Europe and therefore easy to send at sensible cost without paperwork.
Cheers,
Bill
