Help Identifying A 1948-1952 Starter Drive

[8NChris]

A fellow Funk owner told me that he believes Funk used Minneapolis-Moline starter drives. these aren't pulled into the ring gear like were common for Ford at the time. They are shoved into the ring gear as they are today. It looks like a mirror image of the Lincoln / Truck 337 starter drive. There are very faint markings on the body but too faint to even imagine one letter. Does this look familiar?
Thanks, Chris
EDIT: These are custom built starters and the nose cones are said to be made specifically for the 6 cylinder and V8 adaptation to N Series Fords.

All MM used Delco starters except in early 60's when tried Prestolite. If have original starter model can cross to most all drives. No MM used the Ford type starter like on Y blocks.

Thank you for chiming in. I went back and added relevant details I originally left out. Pictured is the nose cone slid in place and the side of the tractor where the factory 4 cylinder starter would have been. Starter drive could be pre 48'. This information came to me second hand from a man who met one of the living Funk brothers in the 1980's.

All MM in 48-51 used same drive if remember right. R,Z,U Just over 4 inches. G drive was longer

That is a place to start.

To me the R, Z and U starters looked about the same. Some of the loose starter drives said to be for these starters had the champher on the wrong side. Can help but think these were flipped images. None of them were exactly of the same design as mine. The starter in the link below looked like it had the same action and champher as the drive on mine. Thanks for helping find a place to start.

One pictured is a Jet Star starter with mechanical/electrical solenoid. UZR use a saddle type electric solenoid. UZR starters look the same but all different Delco numbers.
