Radio Adventures has a Vintage Radio T/R Adapter that you should consider
This kit was featured in a QST article a few years ago, and has been in the
ARRL Handbook for the past few years.
The Vintage Radio Adapter consists of two assemblies, the keying and control
unit and a remote antenna relay. The control unit accepts key, paddle, keyer
or push-to-talk input.

Vintage Radio T/R Adapter (BK-175)
The Vintage Radio T/R Adapter provides automatic transmit/receive switching
for many vintage transmitters and receivers. It provides time sequenced
antenna transfer (with optional remote antenna relay), receiver muting and
transmitter keying in semi and full break-in modes or with push-to-talk
systems in AM or SSB. At less than $ 40 for the entire kit - all components
except power supply, remote antenna relay and enclosures.
