Frameset details
I was told by seller that the original owner claimed it's a Limongi with SL tubing. Only markings are on the Silva brake bridge and "644" stamped on what looks to be a Silva bottom bracket shell. Headset is a Stronglight and apparently original to the bike. Paint is not original. Seatpost diameter is 26.8mm. Any help in identifying the frame would be greatly appreciated. Thanks!
