I think your Morse is a bit later than you suspect. The early Morse machines were 15 class clones, later ones came after the first zig zaggers started arriving from Japan. Morse had his machines built with other manufacturers' designs and was sued more than once for it. Not saying they aren't good machines, just that his models came after others because he copied them. Despite his glowing obituary Morse wasn't a very good man, just a greedy one.
I think the reason I have an unnatural aversion to Morse machines is because I intensely dislike dishonesty. Same with Nelco machines. I do own one Morse clone, it's an almost identical twin to one of my Brother clones and will be a parts donor to the Brother. I also have an aversion to stripping a machine for parts but I don't think this one will bother me too much.
