Most of the listings are vague. There are 4-5 image dissector tubes but hard to tell if Farnsworth lab prototype, TV studio camera or industrial camera use. Also the Farnsworth literature is hard to tell if original or photocopies. I was originally going to bid online but decided to drive up there next week for the auction. How much is the plow blade from the plow Farnsworth drove when he invented television worth?
