While surfing ebay, I came across this Masi GC frame that was already sold. The owner wasn't sure about the date of the bike, but stated the only stamping on the bb shell was "57", no "MC", no serial number. This was a CyclArt repaint. I was just wondering about the lack of the "M" or "MC" stamping. The seller indicated that the frame may have been an employee owned bike but wasn't sure. Just curious!. Go look at item #1147082071, since it has disappeared from the listings both ongoing and completed.
