Ron, thanks for the education. Your knowledge in this matter is greatly appreciated.
I am aware of the Benke-Thiemann stock, and know one of the owners of it (he sports a grey beard

)... but have never seen such an example as this one. I hope the purchaser of the one sold at auction "a few years back" that missed ATF scrutiny... registered it upon acquisition...
If you are in the knowledge loop, please let us all know the outcome of the petition to make it C&R when and if it happens.
My question would be, what Luger would this stock be associated with for exemption from the NFA, and inclusion on the C&R list? The stock would not be in violation of the NFA by itself, and the gun it is attached to in the photo appears to be a standard WW1 DWM Artillery Luger. Then there would be a question on whether or not reproductions of this stock would be permissible with the associated model Luger... or any Luger?
Boggles the mind how this will be resolved.
thanks again Ron,
-John
