Mike, my Purdey is a late, very late, Whitworth barrel hammer gun from 1921. It is a 2 3/4" chamber, 1 1/4 ounce pigeon gun with 30" barrels, side clips and third fastener. I found it in a local rifle store, leaning up in a dark corner, hidden from all the rifles and customers. I got permission to bring all my measuring tools the next day. Everything checked out so it was a quick sale. The gun is all original and fairly high condition. The consignor accepted an offer for a third of the asking price, which was not bad in itself.
