Can any one identify the year of this speedo part?
Has 1959 T1 stamped on it?
It's 1917 or later. The housing number 1959 indicates 2 1/2 to 1 ratio for the left front wheel so it is not designed for a Model T.
There should be a letter-number stamped near the pin that connects the 2 halves. If you can tell us those we can tell you the exact month and date.
You'd be surprised by the demand for the left hand drive 2.5:1 swivel; many other cars used them. If it's in good condition it's a desireable item.
Royce, I'm glad you are using my new Speedometer book...., and you are correct in that this swivel was designed for a 1917-18 Chevrolet and Velie and attached to the left front spindle. This swivel can be used on a right-hand steering (export) Model T but CANNOT be mounted on the right spindle. The date of manufacture is January 1926. Hope this helps, Russ Furstnow
I actually looked it up in your old book.
The new book is fantastic but it was out in the shop when I posted the message.
