The place I used to buy my vintage sewing machine items is no longer in business. I have mainly gone to Amazon, but it takes a long time to search for what I want as there are so many selling basically the same thing with wide variety of costs. It looks like there are only .9 amp or 1.5 amp sewing machine motors. It looks like rather than "L bracket" it is generally listed as "L type bracket"
