Raimey,
Apologies!
one should read the thread before answering
this has of course nothing to do with oldfarmer but a text you posted:

2nd para.: A double gun, percussion system, tube of best quality, Damast Leclerc AND BRAZED WITH TIN; the stock of spanish walnut and the receiver(either bedded or adorned)with german silver (sheet), 85 Thaler (12 £ 25 sh)
So now we know that the 'German Silver' reference does most likely not refer to the brazing, as that is already separately mentioned.
And now I shall have a break and take the dog for a walk

Regards
Günter
