All of the frame markings seem to point to it being a 2nd series gun, with the exception that it has the trigger adjusting screw present, suggesting it to be a 3rd series gun.
Perhaps a 2nd to 3rd series (early) transitional gun might be the best description?
The markings on the LHS are as follows:
Front of air chamber - "Webley Air Pistol Mark I".
Rear of air chamber - "Webley & Scott Ltd Birmingham & London".
Above the grip panel, the serial number - "10010"
And on the breech block - "British Pattent N. 219872" and "Foreign Patents Pending".
The markings on the RHS are as follows:
Rear of air chamber - "Made in England".
And on the breech block - "U.S.A. Patents Pending".
I'd be most interested in the thoughts of other Webley collectors regarding this unusual Mark I.
