Can anybody help please? I need a foresight similar or the same as the pre war BSAs with a bead on the top. Only problem is it needs to be taller than 13mm. I have a couple of cadet major sights and they are just a tad to short, otherwise one of them would be perfect and I don't want to rob one from my pre WW1 LJ style .177 rifles

Please, PM me if you can help.
