General questions about early Lancays

[vzlion]

1. Did all first contract Lancays have a blood grove?
2. Product improved Lancays were supposed to have a shorter sawtooth, the step on top of the blade removed and a black finish. Some were completed with these improvements, minus the black finish, to complete the first contract. Where do the ones without the blood groove, but with long sawtooth spine, the step and the gray finish fit in?
Thanks
