I wouldn’t. Looks like it may have been an enameled paint too (fire resistant) which was a dip and fire process as well. Not worth it unless you were planning to use it yourself. Frankly, it’s nice in just braas
Got quite a few enquires for the ashtray.. was wandering should I get it refurbished to be like the original before putting in the market?
Your are sure it's not a rare solid white gold one?
Are they the original Rolex crown pushers on the tips?
Perhaps you could source some period correct ones to restore to original.
I'd polish the circumfence and the Crown only. Leave the middle as is. Polish / clean with a Brass cleaner only the sides, that are Gold and the golden Crown in the middle. That will bring you more money....
