An explanation of my Photo that Barry H' 'Tossed into the Fray',..Of the 3/4oz of choke I 'Removed' from the Lefever Arms Co."Optimus" 12 bore, Whitworth Steel Tubes.Apologies to "XXXXX" for my error of putting the 'D' in front of Lefever! These 'dealers' are like knives,Some keep their Edge, Some don't)What does a London Gunmaker know about American Built Guns?!!! I am sure that one of the Eagle-Eyed"Webers Warriors" will notice that I opened up the choke .004" more in the left Bbl.than the choke is in the Rt. Bbl.!I also changed the Front trigger over to the Left Lock/Bbl.Then I Set the stock from 7/16th cast-off at the Butt-End, to 3/8th" Cast "IN" at the B/End. Mr Lefty has had me make several other of his 'Shot-Guns'Opposite to Cast-Off Stocks.In answer to Email..JSW.The"Swarff"(Oily cuttings) are inside a plastic container, this makes a great Toy for sticky fingered Kids,of all ages, when in the Workshop, You place a magnet on the under-side of the case,and they can watch 3/4oz of Sir Joes Best Steel Jumping around inside. I think this Gun is pictured in Elliotts Lefaver Books. Crossedchisles.
