The top one looks like it came from a ~1918 Maxwell 25.

Clay A/fordrelic,
Can you confirm the maximum speed reading on the speedometer in your first photo?

Probably not from a Maxwell. Those speedometers were used as factory original on many makes and models of cars, and sold as after-market for anything someone might want one for. The 75 mph top reading would most likely be for a more expensive and therefore faster car as a factory offering. However, after-market buyers were likely to buy anything. The 75 mph models were a bit unusual. It would be great for a speedster, or Rajo roadster!

The other one? I don't have the reference book to look it up? However, there should be a letter and number stamped into the face plate just below the MPH reading. It should be a date code that with a proper reference book would tell you what year the speedometer was made. That basic style flat firewall mount began early 1910s, and continued in after-market well into the 1920s. Several years of brass era Ts used similar firewall mounted speedometers as factory standard or optional speedometers. Standard speedometers gave way to optional in 1915 as the companies manufacturing and supplying speedometers to Ford could not keep up with the demand. Fords continued to get firewall mounted speedometers through the late 1910s until starters became common and speedometers were put into the upper dash panels. Many trucks continued to get firewall mounted speedometers into the 1920s.
Yours appears to be a mid 1910s or 1920s model.

The bottom speedometer looks like a Stewart Model 102 from 1916. I can't make out the date code below the speed drum to confirm the date. See Russ Furstnows' Speedometer book page 53.

Rickd,
I think you are on to something.
I looked at the MTFCA encyclopedia and found information on the accessory speedometers model 102.

The bottom one as you said is a 1916, date mark is H.
The top one is a 1917, date mark J.

Both look similar but have different mounting system.
The 1917 looks to be made to fit in the dash panel.
