T/R
It looks to be a 4 wire T/R coil. I read somewhere that Fisher got his original detector idea from a change in radio signal while flying above large metal structures. T/R is probably the only thing that Fisher ever made. I don't think I have ever seen a Fisher BFO. It would be easy enough to trace out but I just want to sell this one to a classic collector. The model # is T 10-X.

5 tubes
I thought it was a T/R but I could be wrong. From the looks of the variable caps the freq must be at least 100khz or more.

Old Fisher tube T/R
Back when they used these the biggest problem was getting all the finds in the car.

good morning KT: I had most of the older Gardners, first with the miniature tubes. The last one was the 180-c, all transistorized, with the 3' light weight coil. It was a fantastic instrument in it's day. It can still hold it's own for pure treasure hunting.
It was an off reonance type of detector. I still have the hand drawn diagam from one of His engineeers.
This was the instrument that I used to find the 8 muleloads of silver 8 Reales.
