I have a 1927 white rotary sewing machine in a wood carring case that has a serial number of FR3238721 and I can't find any one to give a price quote. The machine is in fair condition and works fine please help

White Rotary machines from the teens and 20s are selling for $200-$500 on eBay.

Do an eBay search for them and put them on your watch list to see what dates (and in what conditions) are selling for.
