I have this speedometer listed on e-bay as a 1919 t0 1925 Stewart 160. But I just noticed the trip reset wheel. The book shows the trip reset to be a small rod sticking thru the dash bracket. I do not want to mis-represent it if it is not as stated. It is also a 2-1/2 to 1 ratio.
I think I may have found my own answer. I think it is a Stewart model 102. for 1915 to 1918. The book states it mounts on the firewall or a Stewart supplied dash. I have the Stewart wood dash for the cars with no dash and it fits perfectly
About 1917. There should be a date code between the words "miles per hour" and the bottom. The swivel will fit many years, for that matter so will the speedo head.
does yours have a nickled plate with it?
No Mine does not have the nickel plate, but it fits the above wood aftermarket dash perfectly ... I do not see a date code on it anywhere ...
The date code (year) is a letter, I think yours is a "J" but it's hard to tell for sure in just the above photo. Take another look.
"J" year is 1917
G = 1914
H = 1915
I = 1916
J = 1917
K = 1918
and so on.
Donnie, it looks like your date code is "J" which would date it to 1917.

I found the date code It is J They did not want a blind old man to see it. A black letter on a black face ...??? That makes it a 1917 and I think the dash I have came out in 1917. From a earlier thread I had about the dash, I believe the wood Stewart dashes came out in 1916 and the speedometer was in the center, and changed to the right side in 1917. .... I ended the e-bay auction as this speedometer will not work with the 1919-25 style dash trim piece. I guess Ill re-list it as a 1915 to 1918 with the wood dash listed at the same time. I believe the wood dash should be correct for the 15s and 16s also as the wood dash was an aftermarket item designed to put speedometers in cars with no dash.
