I don't have Illinois reference material so I always ask questions. I think this HC 18s is a Model 5, but can't seem to find scarcity/value for it. Am I overlooking somethin?

Another shot

Serial number is not clear enough to read.

If it's 2455564;

18sz LS H/C 17J M5 G89

1 of 3520, Ca. 1912

Its serial number is 2455564. It is a nice looking movement with a slight tutone effect. Thanks again Buster

Nice looking movement, I agree to that statement!!!
