Good day. I'm going through some speedometer parts that came with my 1915 RPU when I acquired it. While I am ordering the speedometer book, in the meantime, I was hoping someone knowledgeable would be willing to help with ID of these two parts. Both the large gear and the fiber gear has Stewart Warner imprinted on them. The actual numbers are pictured. On the speedometer drive, the case number says 400 (or 4001?), and the embossing on the drive says "1-1 RH" which I am understanding could mean 1-1 drive, RH wheel?
I'm looking to see if these two pieces are a correct match to work together, and if they would work with any early Stewart speedometer, or if there are only certain models of the speedo that will work with these drives.
Thank you in advance, always interesting to receive assistance from the brain trust that is this message board!

Re: Stewart Speedo Drive - ID assistance requested
I believe the standard drive ratio is 2.5 : 1, using a smaller gear than that shown. The speedometer book will sort this out for you.
