Yes I posted those photos of the Gibbs mounts a while back & have more photos but they are jammed now by RSA 2048 !

I got this one a while back to go on one of my BSA/Lee Speed real or fakes, but like mine with the Dust cover on the early ones & can use the charger bridge on the later types (well some of them) I have a later BSA sporter with this type, but not quite as nice looking as this one .
