That is a good thing to “get over” not having, there doesn’t appear to be many copies of that part left at this juncture. I seem to recall reading the timeline for the brazed pulley mount was after the war, until the early 1950s. Doubtful the factory would have sat on a bike or two that they didn’t have the brazed pulley mount for, if they had a bin of the clamp on pulleys. Functionally, the same.
The 1949 Dawn Tourist I used to have had a clamp on pulley. The brazed on version wasn’t used across the board in that era.
