Also done by Penton motorcycles in the late 60's early 70's on Thier frames that were made of Reynolds 531.
Surprised me when I saw the '531' transfer on the swing arm and frame. So, I concluded straight ga.
I've wondered about this when browsing old English catalogs. The welded frames were offered at a lower price point than the lugged ones. Was the process arc welding, or something else? There seem to be a fair number of them around, if one is shopping for a vintage English frame, so they couldn't be that bad, from a durability point of view.
