I think this is the first F3 handset I've seen come up on eBay ever, regardless of the telephone it was attached to. There may have been some but I don't look at every listing. This F3 is on a WE C-mount Space Saver, the model with the old style, squared off hook.
The handset is described on paul-f's site (http://www.paul-f.com/we300typ.htm#Fhandsets) as "With a pushbutton in the handle. For push-to-talk, push-to listen, amplifier or external circuit control."
Posting it here as an addition to the "handset" section of the Forum's component identification board.
John....you mention a F3 and I find one this morning....looking for something else of course. ...Doug
