It was exported to the Brits under the lend lease act during WW2, then obviously transferred to English controlled China during the Hong Kong occupation period where it was converted by anti-communist double agents of the Ministry of State Security (note the star on the slide) to a 9mm. Very rare and desirable.
That's my educated analysis of what you may have. Post some pics and we might be able to weigh in with some more reliable thoughts.
That's all the pics I have right now. The gun is at a friends gun shop. I will post some more when I get it. Have you seen the star mark before? The gun shop owner told me that the gun is a Chinese knock off, but I believe it is too well made. The serial numbers match on firing pin stop and frame, all the factory proof marks are in the right place, "GHD" and the army ordinance stamp, all the british proof marks are there. He said it was fake and is suppose to say " not english made', mine says, "not english make". Which one is the proper mark? ...and why is the original 45 colt auto barrel now a 9mm barrel???
Alex, according to "The Standard Directory of Proof Marks" by Wirnsberger;
The "Not English make" markings were part of the proof system placed by the British proof houses on arms entering Britain that did not have proofs acceptable to the proof house and surplus British military/US lend lease to Britain leaving service and going into the trade. The particular mark was introduced with the proof laws of 1925 and discontinued with proof laws of 1954.
As you can see from above; you might want to take what the gun shop owner tells you with a grain of salt.
It looks like the gun shop guy is not the one you should be listening to. That is no chinese "knock off"
If hes dead serious that its a fake, tell him I have a "real" 1911A1 that says Regent on the slide that was in the pacific theater that he can have for a resonable amount LOL!
That gun has been around and enhanced, like the double pony on the slide. Who knows who enhanced it, but it is a Colt M1911A1 with apparently matching slide, GHD marked, and apparently Lend Lease at one point. It was not made in China or Pakistan from scratch.
I have seen at least one US&S which was issued to the Shanghai Police after WW2. There were 1911s in China, there were British forces in China before and after WW2. This gun probably has a very interesting history. Condition is pretty bad though. What it is worth is a really tough question.
I think the star mark is of Israeli origin "six pointed star / star of david". I think the horse's on the right side is a German proof mark "Hannover"????? Any help identifing these proof marks would be great!!
