Thanks for the extra pictures, very helpful, I was able to review Scott's pictures, he takes excellent photographs, but not as many as I would like... but a couple disparities were revealed (potentially), his has a Crown/V on the barrel tube or sleeve, forget its nomenclature... but the part that screws into the receiver, there is a C/V at the top. ALso his has the crowned acceptance (only one) on the right receiver, - you do not show it so I assume it is absent?
