I'm no lawyer. But a repro stock used to be legal on a C&R original Broomhandle pistol. They are exempt from NFA along with some Inglis and Luger pistols.
This is a sample letter I found on net. This letter was not in response to a C-96. But you get the idea.

Dear Dr. :
This refers to your letters of March 13 and March 30, 1981, in which you
ask that certain Luger and Browning Hi-Power pistols equipped with
reproduction shoulder stocks be considered for removal from the
provisions of the National Firearms Act.
It is not the policy of this Bureau to render a classification on a
shoulder stock which in and of itself is not subject to the provisions
of the Gun Control Act or the NFA. However, as you are aware, certain
Luger and Browning Hi-Power pistols when accompanied by original
shoulder stocks have been removed from the purview of the NFA.
Our Firearms Classification Panel has examined your request and it is
their opinion that the above mentioned pistols equipped with currently
made reproduction shoulder stocks which either duplicate or closely
approximate the dimensions and configuration of the original stocks
would also be primarily of interest to collectors
and not likely to be used as weapons. Therefore, any Luger or Browning
Hi-Power pistol which would be removed from the purview of the NFA if
equipped with an original shoulder stock, would also not be subject to
the NFA if equipped with a reproduction shoulder stock which either
duplicates or closely approximates the dimensions and configuration of
the original stock.
It must be pointed out that should one of the subject reproduction
stocks be attached to any handgun which has not been specifically
removed from the purview of the NFA with an original stock, the
combination would be subject to all of the registration and transfer
provisions of the NFA.
We trust that the foregoing has been responsive to your inquiry.
If we can be of any further assistance, please contact us.
Sincerely yours,

Assistant Director

Quoted:
I found a 6 digit SN Mauser C96 in 30 Mauser in fair condition with repo stock and holster harness for $650 today. My question is I remember reading something about the use of the stock only being exempt from the NFA if it is the original stock (I know it is with Browning Hi Powers). Am I remembering correctly? If I am, does the ATF still allow people to register them as C&R SBRs or would it be like registering a new SBR? (Ignore California laws for the purpose of this thread please, you will get them wrong, thanks.)
