I agree with Muv ... that machine holds no interest for me.
Although I have two vintage electric machines (a 15 and a 15 clone), I personally want to focus on treadles. For me the attraction is in the pure mechanics of the machines (without electricity), for my husband the interest is in the treadle irons. We are always on the lookout for *interesting* and unique irons, even if the irons only are for sale - we can build a cabinet around it and drop a machine in it.
