Joe, I think I'm going to have to replace that wood...the whole top.
I'll try a filler and see if I can make it look decent, but I'm already thinking that I will probably have to have it replaced. You can see the one chunk of veneer missing under the handwheel, and there's another larger one on the inside of the lid. The base of the cabinet is in great shape...it's got the embossed #24 cabinet...
