The ones I took off looked quite old, but I have no way to know if they were original or not. With that being said, I cut copper pipe to size and will polish it up and varnish as I think it will "pop".
As a side not, sanded the keel down of the old paint and have half of one of the rails sanded. There was no rot on either of the rails or keel. Feeling very lucky because of that. Love the size of those rails. Rather wide and "D" shaped.
