Thanks Dwight,
I knew it was clear to you- just not to me.
Thanks for the additional well researched information.
My conclusion from the same information is that there was a short,
less than 6 months, period of time in which pistol construction could have continued in a grey market manner.
That is to say between the surrender and passage of this elucidating law in Jan. 1946.
I'm sorry you feel this is beating a dead horse, but it is not as
clear cut to me as it is to you.
One thing for sure, we will likely not learn with any certainty
when and by whom this pistol was created.
