Homebrew help
I need some help with a family battery radio I brought back from Illinois. It was my uncles homebrew build in the 20's. I cleaned it and the coils have continuity. Rehostat is cleaned and around 10k. I presume it was a brass 01A tube which I will find around here. Grid leak is open so I need to find its value. Cap underneath is unknown for now. May be .0005. I also presume the four posts at the top (could not get the photos to go L>R) are power.
If anyone can ID the proper connections, I have an ARBE and an AM xmtr to try to make it work for the first time in 90+ years.
