I know Ken Valk of "Wet Goose Marine" has the mold for the wind shield brackets and he also has the air vents and bow light. Here is Ken's email.
If you plan on plating the brass parts your self I would suggest using (copy chrome) instead of nickle. The nickle will tarnish and get dark. The pieces I plated with copy chrome well over a year ago are still bright like the day I plated them.
