Exceptionally hard part to find today, these were introduced in the 1920's National Matches for their faster lock times due to reduced weight, but short lived as it was found that a standard M1903 cocking piece did offer the shooter some protection by way of diverting any rearward venting gasses in the event of a case rupture.
Part in photos is the one you will receive which is critical for those repairing or restoring valuable vintage firearms where item condition, finish condition, and wear are important factors in the purchase decision.
Nice piece of the M1903 story to add to a collection.
