Actually bronze is better as it doesn't get crevice corrosion. But it's so expensive is rarely used. 316 stainless is the best that you'll commonly see, but if its trapped with salt water and no oxygen it will eventually corrode. It's only stainless in the open air.
OK you made me laugh. I have a photo. Can you tell me hoe to post the image?
It's off a Spencer 42-2 built in 1966.
When you want to post your image, clik on "post reply" or if you are on the bottom box clik on "go advanced". Then scroll down and clik on "manage attachments". Then clik on "browse" and pick/open the file off your computer. clik on upload and wait until your file disappears from the "browse" box. That's it.
