If it has the tower for the globe and is complete (reel, little door where hose comes out, and the parts around the hose where it comes out) it is probably worth between $3000 and $4000, and if it isn't beat up or rusted badly, probably nearer the $4000. If it has the globe (the orignial one, not an aftermarket, and I mean a 1930s aftermarket) you can easily add another $400.
I have color ads, color sales literature and a parts manual available for sale, if you are interested email me.
