All the 1200TX's on the records are prefixed with either a P or an R but listed in the registers as M82's arrived from Canadaor sold as M82's to York Guns. Sadly speaking, the numbering and letters attributed to this era of weapons was a "mess" and not one a great comoany like Parker Hale could be proud of, it caused great constination!!
Also found the M98 Sniper S/N S-0001 also sold to Y Guns as a BLACK MAMBA now that is a rare beastwhereever that is now!
