The "Wye" was made by BFR (British Fly Reels) for Orvis, not Hardy. It is essentially the same reel as a Cortland Crown, also made by BFR for Cortland if you need parts.
As far as salt water use with any clicker or to be honest, any reel; you better be a person who takes care of your tackle.
Prompt cleaning/flushing with clean fresh water after use, regular lubrication and a wipe down with a good water displacement product is necessary for long life and corrosion resistance.
If you are they type that puts off tackle maintenance to the off season of when you have time...
...you'll be sorry.
As for me, I do own some modern drag reels but prefer clickers because they most often have the "look" I like and I have never NOT been able to manage ANY fish on one, it's just trickier at times.
