Our catalog record for this one is thin, just the single listing from 1970. We don't have a broader spread of years or a longer run of catalog appearances to point to, so beyond confirming it's a gearbox internal gear, there isn't much more we can tell you from the paperwork here.
If you're rebuilding a gearbox and think this is the gear you need, give us a call with what you're working on so we can confirm it matches your box before you order.
