Welcome to Permies Ruth! I personally don't know anything about spinning/flax wheels but there is a good chance someone around here does. I might suggest checking out some of the threads in this section of the forums:

If you aren't seeing what you have there, that would probably also be a good place to start a new thread with more info about what you have and are trying to figure out. Good luck!!
