Re: 480 on the scrap train near Round Hill

As a trained (pun) morse operator of 27.5 years service in the maritime coast radio service, I'd have problems reading the morse sounder and morse-code version used by the RRs in the US. We used the international version of the morse code and never had sounders in landline service by the time I got into the NZPO run service. However, some small town post office telegraph services were still using sounders when I was a kid.
Our morse key designs didn't have the (horrible) flat top knobs, rather, the NZPO design had a rounded knob, which was gripped, not tapped.
Morse is all gone now, although I still have my personal brasspounder morsekey, an item of historical interest as it dates from between the wars, I believe..
