Ok, that's not an Ashtabula shell, but rather a Shimano "Front Freewheel System" shell. The front freewheel system was used with Shimano's original "Positron" indexed shifting system and has been obsolete for a couple decades already. I suspect that replacement parts will need to be sourced from a donor bike.
