Hi,
I received these for my Marlin from Prime Industries. They also sell a cap that screws onto the bottom drain hole if you want to block the drain. These cup holders fit perfectly and are the stock ones GW uses as Grady Gator indicated. They really look great, especially in the cockpit area where the plastic ones really got beat up from the sun.
The Cup Holder: P/N is 1014PRDI. The Description is SST Cup Holder, Polished Lip and Inside, 316L (92mm). $8.25 each
The Cap: P/N is Closed Cap. The description is the closed cap for the SST cup holders. $0.25 each
The stock drain tubes for the holders to the sides of the fold down seat will not fit. The ID is too large for the threaded drain and too small for the nut that is installed over the threads (still allows it to drain). I ended up changing them with 5/8 ID clear plastic tubing and new hose clamps. A bit over kill, but I wanted them to drain into the bilge.
You can order from:

As Grady Gator indicated, ask for Beverly.
