You might get a better idea of brush plating by googling the term and watching a few YouTube videos.

Caswell and Texas Plating Supply make two nice kits. Pricey though.
Here is more progress. Spent a few hours on the 2/4 minute kit and small pieces. I put lacquer on the crank, as it would be a part that would be handled more, as well as the cygnet bracket. The remaining parts of the machine I have left un lacquered, only wiping them with non-abrasive OZ polish, just to protect them from fingerprints. I left stuff bare because the lacquer adds shine where I don't want it. Also, leaving the parts bare makes it easy for minor touch ups in the distant future, if needed at all. The lid plates were very rusty. Soaked them in Evap-O-Rust, and they look lovely. Will fill in missing gold on them tomorrow. Greased and oiled up motor....runs silky smooth with new belt. I really feel that the mechanism looks like a nice original "as-found" piece.
