All in the eye of the buyer. From my perspective, I love obtaining treadles that must have been brought over from Europe to the USA by the owner. How else would my Pfaff 30 with German manual have gotten here? Not likely imported for use in the USA. Same for my Singer 28 combo handcrank and treadle, Jones CB treadle, Jones Spool treadle...
You yourself say it is lovely. Price is not the only factor. Do you think it is a fair price?
