Oh, well I'm talking about the screws from one of the 1950s Simplex shifters that came with Juy 51 derailleurs and the like. Sorry to be confusing!
I happen to know that my Carlton frame was equipped with a first-generation Cyclo Benelux shifter right before I purchased it using the same mount, hence my confidence that back in the 1950s both companies actually used the same threading - at least based on that much evidence. Of course there's a chance one or even both screws on the shifters recently used with the frame was not original/correct, but I know for certain both were popular and also that the early Cyclo Benelux shifters were essentially copies of the successful Simplex components anyway, and attempting to take market share in England share away from Simplex was a major part of Cyclo business model in that era.
