Hi William. First off, that is a wonderfull clock. I am enjoying your progress. I restore antiques for a living,(appro. 200 pieces a year). As for the case, if I want to keep the original finish on a piece, such as this, I hand rub it with wools wax, using #0000 steel wool. There is also a product that I use, that is an amalgamator, from Victoria House. Both methods will give a very nice finish. As for the brass, I use, toilet bowl cleaner. It cleans very fast, leaving the brass a copper color. Then I follow with #0000 steel wool’
Merry Christmas from Enid Okla.
