The only difference between a bumblebee (paper dielectric like most plastic body tubular caps of the era) and a wax paper cap (also paper dielectric) is the plastic housing designed to keep moisture out. Both suck equally bad. Replace with any decent film caps. Orange drops are good assuming they aren't too old (I've seen nos 60s specimens that were going bad), new production I favor the maroon ceramic coated Panasonic film caps mouser and digikey sell. Good quality and reasonable price.
The yellow caps some of the radio vendors sell are good to despite some disliking their aesthetic. Just don't melt the body with your soldering iron. They are good for restuffing which is my main use for them.
