I just purchased an Illinois 21j model 9 grade 706 and I'm confused about all the model & grades of these. I must have missed something when reading all the threads and the Ehrhardt book. The book says this about the 21j ones.

21j-ON9L-TXPI-1,340-"706" ea(472) $60-90

Does the "1,340" mean that there were only that quantity made of these, can't be, can it?
I only paid $100 , I thought it was a nice looking watch and inexpensive, right up my alley. I know it's not a railroad watch, but it says in the book that they were aimed at "Electric Railway men", that would be the trolley and streetcar line people, I think. Are they not considered some type of railroad, or are they considered more of a bus line? I'll attempt to leave photo's, might take a while.
Thanks for any clarification.
Bill

And the inside of the cover.
Like I said I paid $100 because I like the looks. I've wanted a Bunn Special for a long time but couldn't afford to spend that much on a watch. Whenever I have the money either none available or something happens at home to stop me. This one looks enough like one that I can pretend I have one for a while, until I can get everything to line up right for me.

Bill, if you only paid $100 for this watch you did very well. The Keystone case alone is worth that.

Illinois made so many different named grades and patterns, plus all the variants within grade, that it's tough to keep track of them.

Thanks all, the book had me very confused, as it does every time I buy an Illinois watch. The Illinois database being referred to, is it a book that's available anywhere, like to add it to my buy list. That list is getting larger and larger with every question I ask here, it's okay though, thr more I learn about these mechanical wonders the better!
I did buy it for the way it looks anyway, so I'm happy and the price was great! I'll have it gone over soon during the COA. Need to hurry up and learn to do that myself, keeps me from buying more watches, having to send them out for servicing!
BTW what is the "fat book" I keep seeing referenced, is that the Shugart price guide?
Thanks again gentlemen,
Bill
Edit: Forgot to thank you about the regulator, I hadn't noticed that. I don't have the watch, yet, just bought it this afternoon. I bought a Hamilton from the same man a month or as ago, it's been keeping railroad time since it arrived last month. It's still going out for COA when my other one comes back next week.
