Does it look like this? This is a Model 66 with the "red eye" decals. This decal pattern was only put on the early model 66's, up until the 20's.
your model number is for a 66, allocated March 4th, 1919. The one in the picture is from 1923, and is a side clamp machine. I have another from 1922 that is a back clamp machine.
