Great info Guy's!!!!
I just wanted to add that my fixed bail McCord has the heat stamp on the inside front edge just before where it starts to flare out to form the bill.
Mine in well worn but also has that stress fracture.
I heard that the cracking was very common with the early ones.
I hope to get an answer for my question from the Gent's here that have a wealth of info on these.
Was this due to the type of manganese steel used or was it due to the heat treatment?
