I have an old LSA in 257 Roberts rimmed (7x57Rimmed necked down )which I intend remodelling to a Lee Speed style sporter in 375x2 1/2 and I would like to fit my vintage Pecar 4x to it (traditionalist look away now ).
Is there a side mount scope mount that will fit or can be modified to fit, or does anyone have a mount that they are willing to part with ?

currently on my 7.62x54R Siamese
