Mystery Oil Pump Drive Gear

[MMasa]

I have this oil pump drive gear that I need some help to ID.
It is similar to a JDH oil pump drive gear (relieved on the back side) but has too many teeth.
On the left is the gear for a 1928/29 Two Cam. It has 39 teeth.
On the right is the mystery gear. It has 43 teeth.
At first, I thought that it was for a single but the picture in the parts book for that gear (622-26) has 55 teeth by my count. The mystery gear is bushed like the single ones were. Was there another style of single gear?
Thanks

Could it be from a Peashooter??

Cory,
Good guess! 43 tooth fits 26-28 magneto model singles,the generator gear is around 54 tooth, I currently have 1 from the late Don Berta,he was taking 54 tooth and remachining down to 43,this was the only part I did not have correct inside.

So you can see the differance,between a made gear and an original.
