Ok. I'll take the word of someone who saw the ACTUAL/ORIGINAL piece, that there is the flat part. If so, and these are the twist switches mentioned previously(before these fp diagrams), would they have been an item found only in the UK? Were these props built in the UK? Forgive my ignorance, but I always thought this was the case. If so, and I'm lovin' the footwork so far fettpride, would dimensions be same-same for these generic switches here across the pond in the US? This may be a great re-discovery if many didn't know this.
