Use this site to visually match the found sets, to get an approximate date on them. Usually older is better.

Whatever you do, do not plug any of them in. The risk of damage is too great.
Rather than use "TVG" suggest that you use "rectangular." For the other sets, "double-D" and "round." (The 3 inch Pilot is a double-D.)
TELEVISION SETS:
General Electric (no model number visible) 9-inch TVG screen
Value of this probable 10 inch depends on condition, age and model.
Pilot TV 37 U 3-inch Double D screen, portable TV
National (no model number known) 7 inch rectangular type screen
Motorola 71M-A 7 inch? screen. The screen or its covering is weirdly
melted! <--(Don't worry about the melt in this model)
Hallicrafters Model 505 *with instruction manual* 7 inch rectangular screen
These will bring between $50 and $400 depending on condition and completeness and cuteness, with the National and Motorola (if a full suitcase model) getting the top $, and any set that has channel one.
Andrew Radio "sharp focus" Television
The Andera from $50 to $300 depending on condition and model, if exceptionally rare model maybe even higher.
Zenith model # unknown round screen about 11 inches
Round screens sell well. $50-$300
RCA Victor 630TS 10 inch TVG type screen
$50 to $250 depending on condition. A serial number under C-1000 may bring more.
Another value factor on odd-ball TV's is the presence of all the knobs. I have one rather rare TV that is missing one knob. I'm expecting that knob to cost more than the rest of the set cost me.
OTHER EQUIPMENT:
Dewald UHF CONVERTER model G-300, brown case
Electro Voice UHF converter, model #3300
Super Sonic Television Amplifier, no model number, brown Bakelite
On these, cuteness, condition and oddness are the determining factors.
$0 to $60.
Kodak SLIDE PROJECTOR (complete, manual, carrying case, etc.)
"Extragraphic III AMT"
New old stock projection lamps will often bring more than a complete projector with a burned-out lamp.
New old stock lamp = $30 to $40 depending on type of lamp.
