Wow, an unbuilt BN-1!!
I would love to see the cabinet, panel, and a scan of the manual/schematic!
There’s very little on the web for this rig. 
I have pix on my QRZ page of my homebrew 6J6 transmitter/receiver. I use a 4PDT rotary switch for T/R.
The transmitter is the BN-1 link coupled output. About 2 watts out.

Thanks and 73!

I have a not - built BN-1 and i think before assembling it i should maybe scan the cabinet and panel for replica builders. I wrote "not - built" above because some Ebayites sell "unbuilt kits" which means, literally, they disassemble the kit, supply fresh parts as needed  and presto!

Say, one interesting thing abt the BN-1, trans - rec switching is accomplished by heating alternate sides of the tapped filament  quite like the AN/CRC-7.
