Mr. Parsons, of Birmingham, England is who W.W. Greener gives credit/patent of the chopperlump. There was a simple V-shaped lump, a Dovetail lump which Greener notes will still hold if there is imperfect brazing, then to offset the portion cut-away by the Dovetail, Greener developed a solid steel lump fitting between the barrels, Parson's chopperlump and Greener's last edition of the lump on one barrel, as he prefers the right, which has a "strong dovetail" 3" long and the left barrel is brazed to the right with the lump.

Kind Regards,
