I know for $2,900 this is not a big deal but I was just checking out what appeared to be a nice original Coke 33 but in looking at it I noticed what appears to be a plate with 4 screw where a 7UP embossing would go. With no inside pictures it's hard to say but if I had to guess I would guess we are looking at a VMC 7UP 33 and not a Coke, but for $2,900 I don't think it matters.
