Any help would be appreciated.

Any idea of the manufacturer?

Just a guess but I would say an attempt a economy, I've seen several variations. An old fisherman told me you could open t to allow more air and save fuel. adjusting the carb would do the same thing.

Cleaned up my little unknown engine today and noted that I had an oddball grease cup. Having a matching spare with 1/4 male threads instead of 1/8 female threads, I decided to try a conversion. First I cleaned it up, chucked the hex end in the lathe, cut the off center hole bigger with a end mill. Drilled to size and tapped 1/8 npt enough to hold it, then screwed in a 2 pipe. Rotated it in the chuck, faced it off and turned down the threads. Removed from chuck and retapped from outside end. Worked out pretty good and now have a matching set.

Clever! If you'd used a brass nipple no one would ever guess.

Robert,

I prefer brass fittings, but the other cup has a steel nipple that looks original, so I wanted to match it also.
