I recently turned 60 and here is my birthday present to myself.
A pair of Charles Lancaster 12/20's originally sold in 1933 to Mr. Smith-Bingham by Steven Grant.
Grant took over the business of Charles Lancaster during the great depression. Presumably these guns, started by Lancaster, were part of the sale inventory. The guns have serial numbers in the Steven Grant series not Lancasters. I particularly like the engraving around the serial number on the inside of the fore end iron, something I have never seen before.
