Some of the most beautiful work of this craftsman, and many others, are in this book “Liège Gunmakers through their Work. 1800 - 1950”.

False rifle Pieper Henri
I then unfortunately to tell you only one thing, it is indeed a copy.
Markings are counterfeited, those of the manufacturer and those of the proofhouse of LIEGE, namely:
PIPER I LIEGE Belgium: the true name of this manufacturer is PIEPER, Henri (see insert joint)
PV with the perron in a crowned oval: acceptance with the sharp powder, of use as from February 26, 1968, that does not correspond to a weapon bought by your grandfather seems it represents?
The yearly letter “i” lower-case underlined is the yearly letter of 1970, another anachronism!!
AJH: could be a mark of manufacturer of barrels of rifle but does not appear in the file of the manufacturers!
SIEMENS MARTIN STEEL: should in theory be the type of steel used for the barrels. However names were a little different according to the manufacturer:
At FALLA Jean in LIEGE: Siemens Martin acier martelé CAP (Siemens Martin steel hammered CAP).
At DELCOUR-DUPONT with NESSONVAUX: Acier martelé Siemens Martin (Steel hammered Siemens Martin).
At H.D.H. in LIEGE: acier spécial Siemens Martin (special steel Siemens Martin).
Afflicted.
