Melinda, Joe Caroline & Grant: Thanks for all the replies about servicing the machines for this lady. I will need to figure out a fee but probably not an OSMG fee since I'm not one. I will need to keep in mind the cost of supplies and travel time.
Sad news here in Leavenworth ~ the local sewing machine shop has closed its doors but probably about 8 to 10 months ago. They were a source of some spare screws occasionally plus bobbins, bobbin winding tires and sometimes a machine. She also sold thread and zippers (my main purchases there) and did alterations. It is sad another local business has closed.
