I have 4 different Skelly oil signs. Would like to know how many are there and what I'm missing to complete my collection. I think there are at least two more I'm missing. What I currently have is:
Skelly Products
Skelly Oil Company
Skelly Tire Service
Skelly Battery Service

I can't remember all of them but in addition to those you have there is:

Tires & Batteries
Auto Laundry
Lubrication Service
Brake Service

There may be one or two more. There is two different sizes of all of them too. An 8'6" version and a longer version that's 9'6" I believe. Skellyguy can tell you if I've missed any of them.....GB
