Searching for information. I've read a description that claims Parson's patent No.201 of 1868 was for "chopper lump" barrels. My understanding of "chopper lump" is that the lumps are forged as part of each barrel. The Parson patent reads ... "the lump is made in two halves, one being welded to each of the barrels, and the half lumps being subsequently brazed, soft soldered, screwed, or riveted together; or a lump of the required size may be welded on one of the barrels in such a position that, when the barrels are put together, it occupies the proper place between the barrels."
Anyone seen a barrel with a Parson's patent use marking?
