I am hoping that a member of this collectors "Gentlemens Club" may have a spare screw to fit the Anschutz model 6706 rear sight as fitted to my Webley Mk 3 Supertarget or can advise me where I may be able to buy one as a spare part (a bit optimistic I think).

The screw I am looking for is the large headed horizontally mounted locking screw that anchors the sight to the abbreviated sight mount fitted to the Mk 3 Supertarget.

Both of the side clamping screws are in place - it is only this one large headed securing screw that I need to complete the sight.

I would consider buying a Model 6706 rear sight as long as it was complete with the screw I need although that would be a shame if it were possible to complete the one I already have rather than have to leave it incomplete without this part.
