455 with no manufacture or issue date present, … Model: British Bulldog Serial Number: 93459 Year of Manufacture: 1880-1889 Caliber. I recently encountered a military marked mk iv. Serial number 143, which is in the British Royal Armouries collection, has the magazine catch on the rear of the magazine itself, but serial number 332 has the catch built into the grip frame. Many of these were later sold to the Gardai Siochana, Royal Canadian Mounted Police and also to the Union of South Africa. A five-digit number located on the crane is a production number, not a serial number. The top of the frame is marked British Bulldog, but other than that there are no identifying marks.
