Here's another one - it's short:)     What's the oldest piece of caking equipment you have?     http://www.cakecentral.com/forum/t/744773/what-is-your-oldest-piece-of-equipment

I have some of my mom's cake pans the muffin tins which have to be at least 70 years old.  While not strictly for caking, my Cuisinart Food Processor is 38 years old.  I sometimes used it for cakes before I got a Kitchenaid.  Oh, and Mama's cookie cutters that are probably over 70 years old.

I have my grandmother's 9" round cake pans, pastry blender, mixing bowl set, measuring spoons, pie plates, bundt pan, angel food pan, cookie cutters and nut grinder
