Legnano Serial No.
Hello RETYRED,
Saw some of your responses for DEVIN's original post earlier this yr. You seem to know a thing or two about the italian machines! No serial no. on top of seat tube, but on the driveside of seat tube there is a two-digit number 31. Only other number on the bike is under the BB - says 0129 from what I can make out. There's nothing stamped on the rear dropouts as some vintage bikes I've seen.
