So let's try this again, apparently I can't upload photos due to being new. So I will try to add as much detail as possible my apologies for the length. (Red dit link at bottom)
MY step dad gave me his Merckx Century TSX frame with a handmade in Belgium decal. It's a whole bike with Shimano Dura-Ace components. Modolo Italian handlebars with a weird logo and - EVEN. The only thing I've seen with these components is a team Motorola bike. I have not been able to find this paint scheme as the bike is solid blue with the typical accents in red and white. Chrome lower triangle running along the chain. The serial numbers make little sense to me with the ones on the left almost looking like they were done by hand. Instead of being a straight line stamp they curve upwards from left to right.

On the left 8TTB with a light P stamped to the right of the B
From my research the TT stands for TSX framing which it is according to decals. The 8 the B and the P make no sense to me other than the P may stand for someone in production being involved with the bike
On the right which makes more sense reads D 8454

My stepdad thinks it's a limited edition bike built for a team rider in which he paid a few thousand for in the mid early 90's. I would love any help on this. Link for photos. Red dit. com/r/bicycling/comments/s944vf/eddy_merckx_bike_help/?utm_medium=android_app&utm_source=share
