Was cleaning out my Dad's old shop and came across some old boat shafts that we used to run back in the day. Two of them are 1 1/4" diameter, 5.5' long and already tapered at the end and threaded. I think they are Monel but not sure. (were used in salt water fishing boat) The other two are 1 1/8" diameter and one is 8' and the other 5' long and is just bar stock-not threaded or tapered yet. Not sure what grade stainless they are. These two were to be used in a freshwater mudboat and are magnetic. The other two are not. Any idea what these are worth and/or what they would be good for other than as boat shafts since that isn't happening again.
