I have this 16s Illinois dial and would like to know what mvmt and time peroid this would have been used on.
Thanks in advance,
Michael

Back side feet at 24.5, 36.5, 55.5 Fits 16s Getty that is all I know

Michael;

That works on any 17J like a 186 3FB or similiar HC or OF

People PUT them on 21J samgamos and A Lincolns but not correct 21J railroads have Illinois Watch Co gothic logo as well...I think the 187 17 Ruby Jewel takes a gothic logo too

Tom, Thanks for the information. So can I also assume that this is an inappropriate dial for my Sangamo? (No Gothic)
