First post so descriptions only unfortunately... A couple of years ago I picked up a green with yellow detail MX Leader. Pretty scratched and chipped original paint, with some surface rust, but I was looking for a project frame anyway. The guy I bought it from said it was a custom frame used by a semi-pro Belgium team at the time, I know the number hanger doesn't mean much, but the frame is 54/56, does this mean it is custom, i thought all the standard frames were square 54/54 or 56/56? The serial is L -- D 9551, with the L on its own on the left, so I paid particular attention to this post earlier in the thread:

A long, long time ago, the EMC factory in Meise was getting ready for the new season - 1994. It was the Belgian autumn of 1993, it may have been November, and it was the month in which the frames for professional teams was being built... Slightly earlier a frame was built (for sure) for Jan Schur (Motorola - D9563) and after about a week a frame for Frank Vandenbroucke (Lotto-Caloi - D9674) was built (also for sure).

So a frame built around the time of the two above, November 1993? The colour scheme is the green/yellow in the '94 brochure beside the Team Telekom.
There was a name on the frame that was scraped off...

Second frame is new to me: A -- D3586, size 54, dark blue original paint, doesn't have the MX-Leader fork, and has a pump peg instead of the number hanger. 'A' builder should be 'prototypes to B3000', how come I have 'D' series number? What year would this be?
