I don't collect Illinois you do bro. However, I have tons of Illinois original parts. I maybe able to make the all original Illinois for you from one of the movements. If so I will give it to you so hold off on the Illinois. the 947 will go for huge bucks I think .. that is a pretty scarce Hamilton. What disturbs me is they replated the cases (not what collectors want to see) but if you could nail it ... that is a rare one. Hopefully however no one will notice the unmarked Hamilton is an old 940 and you maybe able to steal it cheap
