I recently purchased a post-war Webley Mark I pistol, in very nice condition, and in it's original box. When checking out the gun, I noticed that the muzzle end of the barrel extended quite a distance past the barrel pivot block, so, I dug out my other two boxed Mark I pistols and compared them to the newest acquisition. What I found, to my surprize, was that I have three different barrel extension lengths. I took a look through the Book by Gordon Bruce, and could find no mention of changes in barrel length specification(s). Since no info could be found, the next logical step seemed to be trying to determine how frequently these slightly longer barrel extensions are encountered.

I have attached a pic of my three Mark I pistols with the muzzles grouped together to try to adequately illustrate the disparity in extension lengths. The actual length is noted for each gun. What I also found interesting, or perhaps just coincidental on my three Mark I pistols, was that the length of the barrel extension increased as the batch number became greater. The gun with the shortest extension has a two digit batch number, the gun with the mid length extension has a three digit batch number, and the gun with the longest extension has a four digit batch number. I realize that there is really no rhyme nor reason to the batch numbers, but I found this quite curious. Could there possibly be some correlation between batch number and barrel extension length?

If you have a post war Webley Mark I pistol, I would appreciate it if you could check the batch number, and the barrel extension length of your gun.

If you could note the details as follows: (number of digits in batch number) / (3mm, 4mm, or 5.5 mm) IE - 3 / 4mm.

Thanks in advance.

I have already received a couple of e-mail responses from friends:

The first one was 3 / 4mm.

The second was 4 / 3mm. (Oh well, there goes my batch number digits to barrel extension length theory...LOL).
