E4746 A - Eddy Merckx Professional 1981/1982, Reynolds 531 tubes , molteni is the color of the frame (orange), 60 is the length of the seat tube measured center-center, NR is the marking of the Reynolds tubes. Frame factory modified for the bar end shifters - first time I've seen this on an early EMC. The bike is beautiful and rare.
B1110 - USA - known, BAZ/YMS - unknown, 2p. chroom - frame chrome pattern, later - frame repainted in EMC (that was the point!), K - the guy who built the fork.
