Might have some véry minor storage markings, but nothing worth mentioning. Frame and fork are still largely in the original wrapping.
FTM stands for Fietsen ToortelbooM. The bikeshop where this frame was picked up from, although it no longer excists. Generic Belgian made frame, sold under their own name.
Frame has never been built up, fully NOS / New old stock, so it might need some minor prepping before building.
Not quite sure which type of tubing was used, possibly Reynolds 531 like some similar frames I have listed at the moment. Or perhaps Columbus SL since the seatpost is 27.2. But drop outs are Gipiemme.
