It's possible someone could help you if you can post pictures of the set, otherwise there's no way to help except to point you at eBay and tell you to keep an eye out. There's many different vintage marble sets.
Ive lost my marble............chess pieces :)

Look at the bottom. Does it say "Made in China". Not saying that is a bad thing as almost everything in my house is made in China and going strong.
Going to have to take awhite bishop,black knight and a black pawn to a marble shop and discuss your options. And bring your credit card as the dealer may not take you serious unless you show signs of being serious about it. Getting marble is not like getting food where they can get it in small portions or an exact amount. ? Idea. Look at other sites where they have marble items. Possible you can purchase it and have them make it into a piece.
ok so ive got this set of crazy pre 1960's carved marble chess pieces that have been in my family for a long time and ive grow quite attached too im missing white bishop,black knight and a black pawn.............the problem these guys are made from some kind of they never made it white and black marble and have an amazing noise when you take pieces and they touch that makes the game some how more pleasurable as you look forward to hearing the clink of victory.so question 3 rare vintage chess pieces maybe someone knows the sets name and i can find it easy or can have pieces made bit i want pieces exactly the same as ones i already have and because i have only lost 1 of the types maybe a repo would be possible and only option
