I have to clarify something that may not have been evident... I was interested in the Nellie because it was from the same period as the Seneca. There is however a BIG difference....the Seneca..assuming it was a screw steamer, was MUCH bigger than the Nellie and as such their propellers and retention systems "Might" be very different. I had to look.
The propeller atributed to the Seneca was six feet in diameter. The current propeller on the Nellie is maybe 18-20 inches. One of the pictures I took (Below) last weekend of Nellie revealed the "Stamp" on the hub of the prop that identifys the Diameter and Pitch of any modern prop. The pitch is 30 inches. I can't see the stamped diameter. BUT it doesn't matter. There is NO comparison with Nellies current propeller and the "Seneca Propeller"
I can ZOOM on MY picture but I think maybe you can't. But again it doesn't matter. NB
