The serial nr 9252 is probably a misspelling.
According their records 9252 has been
"Hammerlessflinte cal 12" delivered "26.9.1902" to
"Riedenau".
I have counted a total of 19 double rifles in 450K
in their records within the vicinity to this 9252.
Besides others also 2 delivered to the
imperial "chamber" (household).
The nearest number to your 9252 are
either 9282 or 9352.
The serial nr is normally threefold, on the
triggertang, the action body and on the barrelflats.
Recommend you to check.
The 2 cartridge gurus of Vienna are gone since long,
one in 2009, the other one late 199x. (My Kalezky
catalogues came from the second one.)
