We are a quarry in bloomington In. and have two beaudry hammers that we r thinking about selling one of them is a No. 12 serial # 17161 and the other one is a No. 8 the serial num tag is missing but I think it is a little newer than the 12 they both run but probably need a little work the treadle is missing of the no. 8 and was just wandering what they was worth and were to sell them. thanks
