Mal-Scots-Skirt Mac Gregor.....The many times you have ventured into the"Museum of Perpetual Mess" an have not seen all those "Purty Purdeys" with the Hand-Detachable Side-Locks stacked in the Racks!!!!Of course, these don't fall to the ground like the Hand Drop-able Westley Richards style, it takes a "Bit of Savy to turn the Purdey"Detachable-Lever" 1/4 turn "Counter-Clockwise" on the Left Lever, then 1/4 turn on the right lever, and then pull the "Lever out of its seating.I have recently Re-Stocked a pr of 20b JP&S that left South Audley(JP&S.HQ.London)with this 'Feature". For the stockmaker,(Note Lower Case for stockmaker, as I was recently told after a "Person of "Gun-Dealing Stature of the Highest Degree" told me my Opinion I wrote of my Importance that the stockmaker had in the building of a Purdey DB Gun or DB Rifle when I was toiling for my "Pennies pr Hr,back in the 1950s,was way over rated!Purdeys could'nt sell their Guns & Rifles if it was'nt for the "Skill and Fantstic Artistic Engraving Carved into the Steel of the Guns & Rifles By the Engravers!! Ha!.... Stockmakers think the H/D Levers are a 'Pain' when it comes to re'stocking. I converted the PR of 20b,s to regular 'Side-Nails' interchangable with the "Levers", Barry Lee Hands matched the engraving on the 'Heads' perfectly......I belive Dr Drake recently sold the pair for the Client that I Re-Stocked them for. Wonder if the HD levers were with the Guns?????cc/dt
