I have a Webley Mk VI made approximently 1916
Mine has a broad arrow on the top strap pointing out the reverse roation of the cylinder
The serial # is 244XXX
There are two crown imprints on the left side of the topstrap side, one with 'GB'imprinted below it and one ithe '29' imprinted below it
There is another crown imprint with possibly WF below it just below and aft of the releasing lever of the 'stirrup lock (?)'
There is another stamp with the crown marking and '28 on the left forward trigger guard, and a broad arrow pointing forward on the trigger itself.
The serial number is repeated on the frame in front of the trigger guard and on the barrel just ahead of the half moon ledge that is just foware of the hinge.
There are several more crowns imprinted into the 'half moon ledge just ahead of the hinge itself ....
On the backstrap itself, it reads 8. 20 with an arrow struck through it.
Below that on the backstrap is a capital Y. that has been struck through ...
Below that (finally) are the letters 51. that has been struck through...
I would love to know any history tied to ths pistol ... my email is on my profile should you wish to contact me otherwise than this thread ...
