Chief, I regretted that post shortly after the fact and am glad to took it well.

What I really meant was that I see nothing in the (reasonable quality) photos that would indicate to me that the guns were restocked. More likely to me, but I am trying my best to refrain from speculative conjecture, Lindner inventoried pistol grip type guards and used them on both styles of guns at the time of manufacture.
Best,
Steve
