Here are the cleats used on most of the 23' boats, Commanders, Lancers, Monte Carlo's too. They are potmetal, as are most of the pieces on these boats. Real chromed brass was left to the big Commander cruisers. Note in this rather poor camera-phone photo, how the corrosion has literally eaten down into the fastner hole area on the left side of the photo, and it looks like a crack. It's not a crack, it is corrosion and it is so bad it is of a structural nature. The Zamak or whatever the metal was at the time, did its job, it was strong enough but it lost the battle with salt water. Many of these pieces will corrode whether they are sitting in a shed in Minnesota or in a salt-water fogged marina on the East Coast. The stuff just does not last that long. For repair, for pieces less corroded than this one they can be repaired and I suppose this one could be too, by sanding, acid dipping, removal of all chrome, and then once the corrosion is all eaten out by acid, by flame soldering a layer of metal over top of the pitted area, and then carefully sanding back down to the original profile, with multiple coatings of chrome,etc. It is expensive but it can be done. I am hoping I can find these new on the shelf somewhere, as I know they must have made many thousands and I am sure there some sitting in an obscure warehouse SOMEWHERE. The task is just finding that warehouse !!
