I already tried the MicroFilm site and Elvis only had the whole
assy. for around hundred.
I think I found the gear only, on Ebay.
I didn't have the gear /small parts web sites. Look interesting .

Thanks EdDataFix

How could you cast a mold for a gear that has a quarter of it missing.
It is plastic gear

the gear teeth is missing.
