Would appreciate some information on a older 12 hammer double I saw at a Mom and Pop antique shop the other day- Marked Prise or Pirice machine Gun on the right side lockplate- hammers, top lever, double bite under bolting- 30" Laminated steel barrels- bores like mirrors, no dents or dings or rust- pg stock and splinter forearm- 20 LPI checkering, no release on the forearm, so must be a "pull-off" design as on my Trojan Parker- good LOP and fairly straight stock dimensions- No other markings except English Laminated Steel on the barrel top rib near the breech- barrels ring well, and both hammers cock and release with good trigger pulls- Any ideas as to maker and aprox. date of mfg.?? Thanks!!
