Doverham,The first illustration posted is the Webley Screw Grip[ie; the screwed bushing is separate from the operating lever and is usually marked,"patent" the bushing is machined to accept the lever].I would refer those interested to page 56 of ;"Volume 2, The British Shotgun," by Crudgington and Baker.Illustrated is T.Webley & T Bain patent 3053 of 1882," The Screw Grip".Reference is also made to Webley patent 1511 also of 1882 rib extension.The illustration that accompanies the patent drawing is a Leeson shotgun featuring a dolls head rib extension and third bite activated by the Webley Baine Screw grip.
Records indicate that Webley Screw grip action was made from1900-1946 and possibley as late as 1950. The action was sold in the white to many makers.
