The Kenmore 158-504 was made from 1963 to 1965, by Maruzen / Jaguar in Japan.
Yes it's a model 50, but this is a generic model number and there's a series of six model numbers within it. Not all were made at the same time. That's why we need the specific and complete model number to get the date of manufacture.
