I have a discontinued Ashford wheel that has never responded well to my touch. It is time to find it a good home & get a new wheel. It is an upright/Castle Single-drive Scotch tension Single treadle It has 4 bobbins The oriface is 1/2" The base folds for more compact storage or travel The wheel is in great condition. I bought it used & have struggled with it for several years. Enough is enough - time to move on. I'm asking $325. with free shipping. I have pictures - email me at firstname.lastname@example.org & I will email them to you.
