Quote History Quoted:
Letter received and reflects caliber as "38/c". Any idea what that means? It originally had a 6" barrel and was blued. It was sold to Winchester and shipped to the British Purchasing Commission, New York, New York. There were 226 guns in the shipment and the pistol was delivered in June 1940.

Back then, Colt often listed guns in documentation chambered in the short .38 S&W as ".38 C" or ".38 Colt".
Since Colt didn't want S&W's name on their guns, instead of using ".38 S&W" they simply changed the shape of the bullet nose to a flatter shape and called it the "Colt .38 New Police", and guns chambered for it were marked "Colt .38 N.P.".
So, this Colt was probably a .38 S&W-.380 British, but would be listed in factory documentation as a ".38 NP.
It most likely had checkered wood grips.
The WWII Plastic "Coltwood" grips were introduced in the early war, a few years after this Official Police was shipped.
Either the cylinder was replaced or simply re-chambered to .38 Special. If so, cases will bulge and may split.
