In a Nutshell
Yes 1941 - not 1946 - was this "Melody Radio Cruiser" ship radio made, by Majestic and Mastercrafters, as research shows. It's in mint cosmetic condition and works fine

Introduction:
Ship novelty radios are discussed in ref.1 (see also pict.26). Best known is the 1939 "Prewar" "Majestic Melody Cruiser" model 1S49, that uses the same chassis and dial as Majestic's Charlie McCarthy radio. Then there are several "postwar" Melody Radio Cruisers, where "Majestic" on the bow's metal tag is replaced by "Radio", that are ascribed to Mastercrafters, General Radio and Television, Imperial, Arvin and others. The wooden parts and the rigging of all these radio models as of several Mastercrafters and Sessions ship clocks, are very similar and were likely all made by Mastercrafters, the individual radios using generic chassis' from various sources. One of them is Mastercrafters Melody Cruiser Model 921, for sale here. The dating as "postwar" seems to be based on an article by Roger Russell (ref.2, taken down), which says "... Mastercrafters went into business just after WWII and it was not until 1980 that they closed their doors..." Following a discussion I started in ref.3 Roger wrote me: "I have not updated my page and will do so. Yes, I should have said Mastercrafters was first incorporated just after WWII and ..." and "Although there is no evidence of incorporation, it is certain that the clock and radio company was an offshoot of the unincorporated Mastercrafters Manufacturing Company dating from 1939". I had noticed that the chassis used for this ship radio is the very same as for a very elusive motion lamp radio model 414, reportedly made by "Radio Vision" (ref.4), that is commonly dated to 1941. Please read the thread in ref.3, where I conclude (up to now unchallenged):

• Both chassis have been made by Majestic and M. R. & T. Corp. Chicago (picts.21-23,25) stands for Majestic Radio and Television Corp. Chicago (St. Charles)
• The Radio Vision 414 cabinet also has been made by Mastercrafters. They should have the know-how from their motion lamps and animated clocks
• "Radio Vision" is not a radio manufacturer, but a fantasy name of this unique animated radio, like "Melody Cruiser"
• The dating of the "postwar" Mastercrafters Melody (Radio) Cruiser has to be revised to be 1941 instead of 1946

About my radio:
The radio is in near mint visual and working condition with all parts being original and only minor paint loss . The rigging shows no sign of corrosion, the line cord has been replaced with a polarized one. The original second antenna has thus been lost. As pict.20 shows this antenna was superfluous, since the rigging serves as antenna too. The radio plays loud and clear with good sensitivity and selectivity.
