You've got some nice lamps there. It looks like a number of Coleman Quicklite Model CQ or Model C's from the late teens to 20's, then an AGM Model P67 from around 1916 with a Coleman 132A(?) from the 30's or 40's; some more CQ's and a Coleman model 117 or 118 (with a slant generator) from the late 20's; and a Coleman Air-O-Lite from the teens. Most of those should clean up nicely, and there's an excellent chance that they'll work again. Watch for stress cracks on the Air-O-Lite and AGM though. I'm trying to find a good fount for my Air-O-Lite...if you want to sell yours...
I've cleaned up a number of old lamps and got them working, the expensive part is getting the glass shades for them. Even replica shades go for big bucks these days, but the prices quoted above are pretty extreme.
Both of these half-frosted shades are replicas, the green ones on the Coleman PQ chandelier are probably not Coleman.

This is a replica or later production Coleman 329 shade on a Coleman BQ bracket lamp (I don't burn it with an original shade - a torn mantle can blow a chip right out of it):

This is a Sunshine Safety lamp, similar to the Air-O-Lite, but a little more clunky looking:

Get out your can of Mother's and go at one of these. In about an hour you could have one burning again!
