I have an all Black 40ยบ BSA 3 speed hub I am trying to date. There are no markings except for the BSA Hallmark/Trademark on one side and a small "L" on the opposite side.
Would I be correct to assume this is a "war years" hub because it is black?
The shifter, that it came with, is top tube mounted , round, Marked BSA and all black too.
Thanks, David Cowie
