Two! That was the first time I saw or handled ONE.

(He also gave me a correct scabbard for my 'three rivet' Pattern 1888 Lee-Metford bayonet. Good thing I was thin and wiry!
The late Mr. H. Woodend was a very intelligent and interesting man. He had a passionate interest in early metallic cartridges, including American ones. I got to meet him again at the Pattern Room, with a group of Canadian Gun Collectors, in 1977. We were able to take him and his lovely wife out to Dinner, in London, a couple of nights later).

BTW - The Enfield Pattern Room is no more. Part of the collection is now in The Museum at Leeds.

Regarding unissued "Jungle Carbines":

When I was about 15 years old (1963), I saw a tableful of 'mint' British Jungle Carbines at Berry's Army Surplus in Detroit. The price was $35, each.

At Michigan Antique Arms Gun-Shows, the 'Jungle Carbine' was a common item in the late 1960's and early 1970's. They often appeared unissued and sold for $35.00.

My first Jungle Carbine was an early one, that had been used and poorly re-finished. Around 1969, I sold it for $35 and bought an 'unissued' one for $35.

Gun prices use to remain unchanged for years. Your Dad got quite the bargain for $17.50. You want to double his money?!!!
