1. Do you know the serial on this? As in, assuming this is how do you know it's a 1989 specifically?
2. I'm also assuming those are the original decals, with the bird Merlin logo on the downtube decal. Would this year originally have had the "Titanium" on the top tube normally, too? Or the 3-2.5 decal on the seat tube? Or was it normal then for it to only have the head and down tube decals, as yours has?
Sorry, trying to figure out what decals I need for my own (supposed) 1989.
