Very tough watch to find and you are correct with 100 made. The movement plates look nice and bright with nothing too distracting in terms of marks and this is a big plus in favor of your watch.
Unusual dial to find and from memory I don't know if I've seen one marked Illinois that was exactly the same, particularly in the hunting case Model 8 version. Are the correct dial feet intact? No sign of the center chapter having been replaced (altered solder no the rear)? The reason I ask is that many of the hunting case Model 8 movements have dials with a missing or altered foot, or messed with center chapter, as they have one foot in a different position than the common open face models so there aren't enough good Model 8 dials to go around for the movements that need them.
Case is interesting with the Burlington markings, this does correspond with the dial numerals in the outer chapter which are a typical Burlington style, but I don't recall anything similar with a non-Burlington signed movement matched with this style dial/case so this is a bit of an oddity. In terms of value probably doesn't have much influence either way.
As far as value … I've seen a 19J 16s Bunn hunter bring as high as $4000, but this was in a stronger market and the watch had a very attractive and top condition dial/case. Today I might see your watch at potentially about half this level, so perhaps around $2000-ish to an IL collector that understands and wants it.
