I am building some naval bronze Coleman Super V Color machines. I have 10 frames I will build to your specs or mine. They come with RCA and clip cord power connections and weigh 7.5 ounces and thats light for bronze. I hand wind all my coils and use 1018 steel for all my magnet components. I wind in 24 and 25 gauge [old school] wire and use the best money can buy from the USA.
