[GreenKeys] W2BFD Information??

[Jack]

I would really like to get a copy of the schematic for the 1950's
vintage terminal unit/converter designed by John Williams, W2BFD.

As far as I can tell, it was the first real Ham RTTY terminal unit
developed after WW II and W2BFD was a major influence in
getting Hams onto RTTY on the VHF bands at the time. In fact,
I would like to learn a little more about W2BFD in general.

The TU used octal tubes, probably 6SN7's and 6SL7's, home made
filters and lots of relays. Any help would be appreciated.
