Along that line, I needed a replacement cam lock screw to replace the buggered headed one on my Mark IV. I found someone who could make one and blue it to match the Webley bluing but when it arrived it was for the Mark VI instead of the smaller IV.
Now the cam is a really low stress item, it is just the post for the cam that works the ejector when the cylinder is opened. What I found interesting were two factors, first, how much bigger the VI cam lock screw was compared to the IV...
... and that both slots were designed to fit and be turned with a common Two Pence with the bottom of the slot concave to match the curve of the coin instead of the more normal flat head seen on all the other screws.
The advantage was that once the cam lock screw was removed the whole cylinder could be easily lifted off the frame for total cleaning and without any tools other than what the average soldier or policeman would have in his pocket. The size and content of the Two Pence was the same throughout the British Empire so it would not matter if it was an English or Indian or Australian or Canadian or Bermudian or Burmese Two Pence.
On my H&R Defender which is a slightly newer but similar design top break 38/200 or 38S&W revolver and from about the same era as the Webley Mark IV you just open the gun and pull up on the cylinder while rotating it until an indent lines up and it lifts free.
