Thanks to all for your interest.
W. Röll made that rifle for a French officer circa 1946/47.
The 2nd DB of Leclerc (1) occupied Oberndorf first before French put their own administration at head of the works, Walther Röll and Walther Gehmann choosing freely to work with the new occupying forces.
During that period many sporters were made for French officers, using disparate parts in stock, and amazingly the firm accounts department took great care to invoice every rifle ordered by Frenchmen for their own use !
That one use a kurz system modified with what seem a sleeved heavy barrel, the new bolt head being modified with a separate off-centered light firing pin, stroked by the shortened original one.
No other modification were made on that action.
When I could get some time left I will try to return with more photos after full dismantling…but be patient because I'm overflowed by work !

(1) for info, Marechal Leclerc grandson is one of my best friends.
