Help id'ing distributor angle drive

Hello

I have this distributor angle drive, but I don't have the distributor to go with it. More specific, I don't have the dissy gear that matches the drive gear. First I thought this unit had the same driving and drivven gear but the distributor gear's diameter is slightly smaller. Maybe 1" for the dissy gear. I think the drive gear was about 1.1".

Anyone recognise it? That would help me find the correct gear. I'm guessing it's from a tractor, industrial engine or maybe a military vehicle due to the paint color. On the other hand lots and lots of older engines were painted green.

Thanks,
Magnus
