Hi Steve, sorry but I always seem to be jumping in, only because I have been through all your problems!
Genuine chrome fittings are all but impossible to find, I tried for months and months, the next best alternative is nickel plated, good quality ones are a very good compromise.
There are plastic alternatives, but I thought they looked cheap, and all the so called chrome paint is just bright silver, with the exception of alclad, very expensive, but does what it says on the tin!
My winch is a graupner nickel plated, the deck hooks are chrome plated from scoonies hobbies, the big find were the cleats, aeronaught chrome plated (could be spelt wrong), the front chrome bumper, the chrome plates for mooring ropes, and the corners of the transom are all chrome sticky back plastic, mounted on thin plasticard, the chrome rivets are dressmakers pins, the vents I vac formed myself (all details and pics in my huntsman build log), chrome window frames I settled for humbrol aluminium paint, and buffed it up, thinking bright chrome might look tacky, however, on the refit I will paint with alclad chrome paint like the vents, grab rails and posts are stainless steel, most model train peeps have these, I cant remember my source, the chrome front fender Steve at Scale Hobbies in skelmersdale had custom made for me, and after all that, I sailed in salt water and tarnished the lot
