[Morrow] Production dates of Morrow models

[John King]

Any Morrow experts out there who have a chronological record of production of  the various Morrow Models?

I heard my first Morrow transmitter in 1958. I GUESS it was an MB 560 and it was in a Mobile set up out in the Western part of the U. S..

I bought my first piece of Morrow gear used from Henry Radio of Butler, Mo in 1960. That piece was a Morrow MBR 5 receiver and vibrator power supply. I, like a nut, sold it in 1961.

Now I have converters (5BR and 2BC 10/75 mtr), an FTR, MBR 5s, MB 560s, MB 560As, Mb 6, MB 565, but do not have a very precise idea as to when each was made. Anyone have a history of Ray Morrow and Morrow Radio of Salem, Oregon other than the article in Electric Radio of a year or so ago?

I will be very happy to communicate with you. Thanks and 73, John, K5PGW
