I really appreciate all the information and am glad to be able to fill in the gaps with unknown information. Hopefully this isn’t too boring or tedious, and some of these offer at least a bit of interest. Today’s Merckx is one of my favorites. It is my Motorola MX Leader. I picked up this one on a trip to Oklahoma City. I was told by someone that this is probably an early MXL because on the seat stays. I have seen in the past someone has the records of the Motorola team frames, and though I have no reason to believe this was one, it would be pretty cool if it was at least from the same batch. Bottom Bracket stamp: L D1097. Again, thank you for the information!
