I don't think yours fits in with that info at all. It looks to be from about 1980-82, and maybe even later. I don't know when they went out of business. Might be Columbus sl, who knows (I think they might have used it in the 80's), maybe someone smarter than me. I do know that that is a pretty nice looking Mercier. Most of the ones I have come across are all from the boom of the 70's. I would assume that that was the top of the line for the time, but I don't have much to base that on. Anyways here is a photo of what people who ride Merciers look like.
