I don't have much Signal, but I did restore a Wayne 60 as Signal, put a display door on the front, made glass shelves, and lit the inside. I have a few Signal items on display in the pump. The five gallon grease can sitting by the pump has a small "slit" cut into the top. It looks professional, not home made. I purchased this can and several hundred "coupons" years ago at the Pomona swap meet here in Los Angeles. This was used by a dealer in Santa Paula, Ca. (Dick Bennett's home town) His customers would get a coupon, tear off a small perferated portion, and put the remaining piece in the five gallon can. He had a drawing for prizes. Some of the coupons are marked with his business name, and some are blank.
