Atalanta & Worldspan
Nick/GBxx-GTZD-VP8IY-ZHFxx
was an Atalanta which seems earlier than most suggested dates.
The Worldspan was simply an Oceanspan plus amplifier. The Oceanspan on
its own had about as much penetrating oomph as a fart in a
thunderstorm but when used as a driver for the amplifier output was
around 700W on some bands (perhaps more). The amp was in same sized
cabinet so stylewise the pair looked fine.
Marconi Marine gear looked very pretty but with few exceptions I was
not enamoured.
One small shipping company I worked for had the quaint idea of simply
buying the best of everything so that ships with 50's/early 60's radio
gear had Redifon main receiver, IMR transmitters, Redifon auto alarm -
which actually worked unlike the Marconi junk heap, Marconi d/f -
which was one thing they consistently did well, Kelvin Hughes radar
and echo sounder. They also paid their R/Os considerably more than
even the top whack a few radio company men got.

Theres's one with the optional synth on UK eBay atm I was looking at.
I don't have enough room left in the rack for it so it would need
some re-arranging if the shack. I'll think about it!

I have added your 1956 date for the Atlanta alongside the date range
documented by Fred Osterman. If the Atlanta was already in the school when
you attended, that would make the in- service date slightly earlier. In the
document, I've asked for collaboration for the in-service date.
Radiomuseum.org shows a circa of 1958?? Which indicates uncertainty to me.
This date will get nailed down eventually :-)

Hi Nick and all. Abt R551 rcvr
In 1975, Fina Italie/FNVT built in 1975 in Feyenoord Shipyard in R'dam had a Redifon equipment and a R551 rcvr (see img279). It was my first rcvr with direct displaying of the frequency. But it gave me some headache, cos at this time I wasn't familiar with PLL technology. In 1976, the company decided to install radiotelex o/b FNVT. For my manager the main principle was ''the cheaper, the better'', therefore we rcvd an interface fm Redifon, a modem fm SAIT and a tlx machine fm Sagem thru a French cy which was supplying us with spare parts. I had to make do with that during drydocking period. I was not vy satisfied with R551 in tlx mode. You had to use it in SSB mode, therefore the filter didn't match the tlx bandpass (i.e. 2,8 KHz for SSB instead of 500 Hz for tlx). So we got another receiver and were using the R551 for CW (quite good for this mode) and the other rcvr for tlx.
Then when later we received another transmitter and receiver fm SAIT, the R551 ended its career in the brooadcasting system (see fnvt9)
On the other hand, the Redifon Auto Alarm always gave vy good result. It was working so well that vy often we called up in the middle of the night by the AA hundreds of miles fm a distress.
In 1971, two VLCC were built in A'dam and completed in R'dam for Petrofina Cy: Fina Britannia/GOUU who became later (in 1979) Fina Britannia/FNLW and Fina Canada/FNGC. Both of them were fitted with Redifon equipment. The first main rcvr didn't last for long on both tankers (t'was not a R551). It was replaced by another rcvr, much btr than the R551. I think I have pictures of both. Will send them later, mebbe it will remind some of you of good old time hi.

Snd mail today
about the 2 Redifon rcvr installed o/b GOUU and FNGC, pls find two pictures (sri vy bad quality). The first rcvr (see joined file before) then the one that replaced it (see joined file after).
Above the rcvr on snd photography, there is an interface Redifon installed later by a RO permitting to connect a line call thru a shore stn to anybody in his cabin. It was a good idea, but sometimes it cud cost an arm and a leg when the guy in his cabin forgets that he's on board a vsl talking to his wife or girlfriend thru a coast stn.
Any of you knows these receivers?
