Sorry, I cannot help you with the parts you wish. If you consider new production of these rare R&P gears, please let me know.
Five years ago I had a major crash on the drive shaft, the ring and pinion gears and the rear end on my 1922 Four-Ninety, the first year with the spiral cut gears, same as on 1923-1924 Superior models.
Maybe you can have some help from my thread
I also made an inquery about new production, see this post
on the 1912-1928 forum and this thread
on the 1916-1922 (only 490) forum.
After some time I was lucky to find a combination of good used parts and, actually, one NOS ring gear. I installed them and since then I have been putting on 3 000 kilometers, 1 800 miles, so far without problem.
But who knows for how long? Therefore, maybe I can be interested in buying a new production set, if the price is reasonable. Also, I know a qouple of guys here in Sweden who maybe can be interested.
Anyway, good luck!
