Although John did have his cranks nitrided, as I understand it - a number of cranks went missing around the covid time, when a series of crank manufacturers stopped trading. It is possible that some of these may have re-surfaced and could have been sold on.
I take it that is a pressurised crank, I notice no drillings in the oil pick ups.
