Great photo and thanks for the response y'all. I had never heard of fishpaper before; maybe I can get something rigged up that looks halfway decent. Again, many thanks for all of the help provided in this thread. My station is miles ahead for it. There may be a more technical name for the "fishpaper". That was the name that the old time engineers, that I used to work with, called it. We used to use it to insulate the hot side of switching power supplies from ground.

Sandbagger is right on the fishpaper. It's used for insulation. Back in 1965 we had High School electronics and we would wind our own power transformers from scratch. A layer of fishpaper would be wrapped around the windings and then the next winding would be done. It's a brown heavy woven type paper. I'm not sure that I would even call it paper.

By the way, not to confuse, they made different grades of fish paper too, so cbrown's picture of the mic's battery insulator is actually a heavy grade and different color of it than we used to construct power transformers. Some may confuse this type with cardboard. I think they're still using fish paper between the wire windings of transformers. You usually can see the edges of it in the transformer. Maybe they've gone to some other insulation like flexible plastic, maybe not?

Tombstone is right, the battery 'box' on the early Turner +2's is heavy fish paper.

Roger that, thanks guys. I haven't had a problem with battery drain since I took the battery out of the uninsulated housing, d'oh! I'll rig something as time permits.

Congrats on finding the battery drain. Good luck on making a battery holder.

(***Ruminating on whether to use Haddock, Silver Oriental Carp or Cod to make the fish paper....***)

Icelandic Cod, ha, ha. Earlier I posted that I have a +2 that has corosion on the battery connector and heavy corosion on the battery holder. My mic has the plain round silver marker in the center of the element screen and just marked Turner +2. The push bar is marked SSB +2 Transistorized. cbrown's picture of the bottom is different than mine. The relay/electronic switch is in a different place and I see where I almost made a mistake. Someone has obviously made a battery holder out of metal and pop rivited it in. Sloppy job too and that's where the brunt of the corosion is. The edge toward the switches is pressing tight against one of the leaf switches insulators and probably touching against one of the switches too. I didn't notice until I read these posts and was going to make another metal holder for the battery. Forget that, I'll remove the metal one and once everything is cleaned up I'll form one from a piece of gray fishpaper that I have and pop rivit that in, making sure that my construction insulates the battery from the switches. I almost goofed.

I was traded a newer +2 this weekend, let me shoot a photo of the bottom. It just has 'Turner' on the pushbar. Other than testing it to make sure the element worked, I didn't look at it too much.
