If you go to Jason Baxter Wizard Outboard site and go to Tech you will find some date on the prewar Sea King outboards. I thing enough to pin
down which twin model number you have. That may be useful in tracking
down a decals.
Good Luck

Edit Montgomery Ward Sea King brand outboards were made by Evinrude in1938 to 1942 prewar period, except for a price
leader single made by Thor / Kiekhaefer.
