FN GP (HP) 1935

[RockinWR]

E.,
* My guess is the S/N is 88071a. The "a" is a small lower case letter.
* A single close-up picture of your friend's S/N's on the right side frame/receiver/barrel might confirm my theory.
* The WaA140 accepted WWII FN HP's are well known over the entire "a" block.
* Probably an Oct. or Nov., 1943 assembled HP.
Respectfully,
Bob
