Just joined this morning, and was searching around for an answer, but couldn't find anything specific. I bought a used 590 Mariner recently and have been trying to find out how to determine if it has the stainless or marinecote barrel and mag tube. The receiver is aluminum and trigger group black plastic, no bayonet lug. A magnet sticks to the tubes.
It looks like stainless to me, compared to say the standard kitchen knife, but I'm not a metallurgist. I've emailed the company a couple times but no reply from them. Other Google searches were fruitless. Is there a serial number range that could be used to help figure this out? Mine is Ser No. (partial) K680xxx.
Anyway, here's a couple pics.
