Gents,
This is a very nice document because provide at the same time the signature of Borchardt (quite rare indeed) and E. G. Westcott President and Treasurer of the Sharp Rifle Company (below a letter signed by him with also his head letter).
By the way, the first traced evidence of the Borchardt in the weapons field is actually a letter Borchardt wrote to Westcott on the 18th March 1875.
Due to the amount of money, this is a payment for the royalties of the patent for the Sharps-Borchardt rifle that is dated 1876.
Very interesting document.
Cheers,
Mauro
