Arrh, that may be the case, Haloed and HJ, those Webley 700 guns, and I've also had a couple or three.
But in true terms, yes it is a good gun, although with some design faults (see below) , but no, it isn't what is termed in the trade a "best boxlock" in how it is built. Irrespective of the strength of the metal or quaity of the engraving.
In fact the interwar BSA boxlock ejector in some of its grades, and there were many, has and had more of the features of a "best boxlock" than the Webley 700.
And until the spray hook welding method became used they were always not as simple to rejoint if off the face because of that. So it's a good gun, as said, but not in gunmakers' terminology a "best boxlock". I have seen a prototype that Webley did of the Model 700 that did have a removable cross pin.
And I think even the later W & C Scott Bowood and Kinmount were intended to have that removable cross pin but didn't. Whereas the Holland & Holland Cavalier did have such? But I'll happily be corrected.
