I have a late double spring clip, No.675 I think, in its box and hardly used, which does not have the projections, and looks for all the world like it never did have them.

SO: Either both projections were broken off on a pistol which has seen very little use, and then expertly repaired and blued over by its owner to match the existing action?

OR: Webley decided at some point, probably fairly late on in the making of the double spring clips, that the projections had a limited function and removed them during manufacture?

OR: The pistol was sent back to the factory by the owner because the projections were bending or whatever, and Webley 'fettled' the pistol at that point in time?

I am open to suggestions?
