My Singer 237 & 15-90 share the 1895 coffin top treadle cabinet and it works just fine; both have their own treadle belt since the belt that fits the 237 is too long for the 15-90. As long as the machine bed and the hinges line up with the cabinet properly it will work, both your 15 and 66-1 are full size Singers.
