old Dumont CRT

http://www.ebay.com/itm/261383140357...84.m1423.l2649

I ran across this "DuMont Teletron" while searching for rectangular CRTs, looks really early to me. Anyone know what it fits?

Kinda looks like one of the ones in that familiar prewar pic of the gal holding 2 CRTS, a 14" & a 20"...

Actually its part of an early tube based Flux Capacitor Time Machine, obviously there were no Delorians around when this was made, so I would guess this came out of a Stanley Steamer time machine before 1913...... Part of the time wave had to be monitored on a screen so the user wouldn't end up somewhere they didn't wanna be, like at a Justin Bieber concert in 2012...

Definitely a pre-war tube.

Yep, before the 14AP4 came out there was this one. Should go for big bucks, especially if it's good.

Notice the glass cracks formed around the element support wires and connections going to the base inside the tube. This says to me "I'm all air."

Probably, but perhaps it can be rebuilt someday? I keep telling people to hoard their empty jugs, I suspect one day I'll see many of them myself in front of a vertical lathe...
