The Brits established the Royal Flying Corp early in WW1. Pilots were trained and transfered from their regular regimemts, "on loan", to the RFC. which explains why photos of the pilots often show them in uniforms of enlisted men or officers of Artillery, Cavalry, of Foot regiments, etc. Later in WW1 the Royal Air Force was establish as a separate unit of the British armed forces. Smith & Wesson Triple locks and 2nd model .44 Hand ejectors were issued to these pilots. Regulations required the unit armorers to stamp these revolvers with the date issuance to a particular unit in the military, the unit designation, and the unit's inventory , to rack, number. I have about a 1/2 doz. of these guns in my collection, plus the uniforms and aviation gear of the pilots. ( I need a Spad & a Sopwith Camel and a Fokker tri-Plane to complete the display!) A friend of mine has about the same amount of these guns, etc., so someday we will do a joint display for the annual meeting of the S&WCA. One of my guns, a T-Lock .455 cal., serial No. 800, was examined by David Penn, Curator of Exhibits (ret.) at the Imperial War Museum in London. He said it was the best example of a WW1 isssued T-Lock to the Royal Flying Corp. he had ever seen, as it has all the stampings the regulations required. Often, due to other pressing duties, the unit armorers did not take the time to fully stamp the incoming revolvers before the pilots got the guns. It is stamped with Crown proofs on the barrel, frame and cylinder. The butt of the left grip is stamped "53 S' for 53rd Squadron. The butt of the right grip is stamped "RFC 29" for Royal Flying Corp, gun # 29" The 53rd Squadron flew in support of the Bengal Lancers and Lawrence of Arabia in the Mesopotamia campaign against the Turks. This T-Lock was shipped Oct. 29, 1914 to Remington Arms Union Metallic Co., ( REMAUMC) agents for the British Gov't in the USA. Later shipment of the the 2nd Model .44 HEs to the Brits, in my collection, received different stampings. No proof marks, just the military acceptance stamps and the rear of the frame, at the hump of the back strap, is stamped with the date, squadron and gun number. For eample: Ser. No. 48259 is stamped "6.16 over 8RS.RFY over 15 ' Three lines of stampings, meaning "June 1916, 8th Recon. Squadron, gun No. 15" Holsters for these guns are of the Sam Brown type. Regulations, Old Boy! Pip Pip and Tally HO! "If I can't pot a dirty Hun with my S&W, I shall point my swagger stick at them and go "Bang. You're dead!" Ed.
