Here is a guy that sells decals for Coke to put on the face. item 290560304221..plus others Mobil, Shell Amoco.. etc. What about this Harley Clock, looks fake to me item 200624341065, and this Hurst Clock face looks too white to me item 190545416002.
I've been to the guys house that is selling the harley clock (i bought a coke button sign from him) and he buys pam clocks and puts new add glass (or stickers or whatever) in the pam clocks and resales them. He is upfront about it and from what I see in his listings he discloses that info.
