I came across a photo of this swivel and fiber gear. The bracket looks like 1915 or so, but the strait drive swivel and large fiber gear are throwing me off. Is this model T hardware or for another automobile of similar vintage? Just curious to see what the experts say. Thank you in advance!

The "direct drive" was used with speedometers that run 2008 rpms at 60 mph. These speedometers include Van Sicklin, Warner, Jones, Johns-Manville, Sears Cross, Standard Thermometer and early Stewart and Clark. I suspect this drive was used on a Van Sicklin, but have no proof without studying the unit closer. Phil Knighton reproduced these drives as a substitute for fragile 1:1 ratio swivels.

The "S" clamp is a brass reproduction and has no bolt going through it to tighten the clamp to the drive or "L" bracket. I hope this helps. Russ Furstnow

Russ, thank you so much! I really appreciate your response. I should have added in my original post that I do have your MFTCA booklet "Identifying and Restoring the Speedometers used on the Model T Ford", but this particular set up had me thrown off, and so I asked. Over the last year or so, I've collected some heads and parts to replace the long lost speedometer on my January(ish) 1915 Cut-down touring. It's ALOT to learn, and I am appreciative of folks such as yourself whom have taken the time to collect information for the rest of us to build off of.

Russ, one more question, if you do not mind. Would the swivel and fiber gear, if paired with a 58T 8P wheel gear, work to drive a 1916-ish Stewart Model 100 with a black face? Head would be similar to the head on page 26 of your book.

Thank you in advance sir!

Andy

Andy, The short answer is no. The Stewart Model 100 would use a 2.5:1 swivel. The drive you show is a direct drive 1:1 ratio. Also, a 58T gear is used on a 21" tire. I hope this helps, Russ Furstnow

Russ, again, thank you very very much. I really appreciate your being willing to share your knowledge. I had been wanting to contact you in regards to some other assembly parts that I have. Would you mind that, and what would be the best way to reach you?

Thank you,
Andy

Andy, I sent you a PM. Russ Furstnow
