White Rotary Sewing Machine


The above page has a link to a manual, as well.

Value is subjective as it is determined by several things, ie visual condition (wear & tear), operational condition, the accessories included (presser feet, owner's manual, carrying case, etc), rarity, its geographical location, and ultimately, how much a buyer is willing to pay. There were a lot of these machines made (good machines though), so their rarity may not be great. Unless the machine is in pristine condition, most people who would want this machine would plan to use it to sew, not so much for its value as an antique, etc. You can check auction sites for recent listings and sales to get an idea.

I have a few of the old White machines and it is never obvious as to how they are threaded. I found a YouTube video demo of a White and the fellow does a pretty fair job of showing how to thread the machine. I will include the link. https://www.youtube.com/watch?v=j9eiKXCjv80 Threading White Rotary model 43 sewing machine
