I have a Illinois 16s 19j model 9 grade 706 ser.#2588463 that has a true center bridge Is this common with a grade 706 I ran the ser.# thru the Illinois data base and It says nothing about a true cntr. bridge all ser.#s match.
thanks

Albert,

That online database isn't much good for details on mechanical features. The Meggers & Ehrhardt Illinois Watch Co. Encyclopedia is the real authority. On page 140, the Grade 706 writeup says nothing about false bridge movements, which tells me they were all true bridge, total production around 47,000 for the 19-jewel version.

Thanks Ed
Al
