[Boatanchors] Just another hacked ARC5?

[WF2U]

Incidentally, on another list, someone has a 2Q4 phase shift network. If someone got that transmitter, this would make the restoration easier. 
I'm pasting the email here:

If anyone is interested, I have a few parts that I will give to someone who 
wants them for postage and an envelope.

1. B &W audio phase shift network model 350 type 2Q4. And it is in the box 
like new.

2. Plug, octal type without shell. It is a 9 pin version

3. Plug, octal type without shell it is the 11 pin version.

Anyone interested?
