I think this thread sort of serves as a history thread. If memory serves, this is the 3rd run of the 77 barlows.
The first run had 2 mains, a swedged clip and a wharncliffe. Nickle silver bolsters and liners. If memory serves it was available in old red sawcut, tan sawcut, blackwood, and maybe autumn gold bone, memory is foggy.
Second run was all single blades, available in long pull clip, long pull sheepsfoot, and wharncliffe. Same cover choices as the first run I believe.
This is the third run, long pull spear main, single or coping blade behind. First run with all steel hardware. Same cover choices as before with the addition of natural micarta and smooth ivory bone.
