I messed up.

I am rebuilding four Maka mortisers, I removed the motor tags and forgot to mark three of them and which motors they came from.

So can anyone help me to match the correct tag to the correct motor?

The motor tags;
#1. 600volt, 60 Hz, 1.90 Amp, 1.3kW, 3420rpm
#2. 600volt, 60 Hz, 1.90 Amp, 1.3kW, 3420rpm
#3. 550volt, 60 Hz, 2.10 Amp, 1.3kW, 3420rpm

The motors;
Each has three wires to the terminal box.
The resistance reading across the leads is consistent across the three leads in each motor. Each motor reads different.
I expected two motors to be the same and one motor different, not so.

Motor
#A. 12 Ohms
#B. 13.5 Ohms
#C. 15.5 Ohms

Which is the 550 volt?
And why the difference in the three?
