Another mystery frame I found. Colnago Super with internal cable routing for rear brake. The owner said that was made in 1979. I was very confused, because I haven't seen Colnago frame like this. The paint job was poor and it was without decal set or just what was left of it. I repainted it, but the frame was originali red with similar decals. I saw this bike on some old pictures from the end of 80s. Pictures were old and not in a good shape to see the cable routing. When I get started with this project, first I chemically put the paint stripped off and carried it to an old frame builder, who told me in Italian " E' nato cosi. " - It was born like this.... Than we try to find something around lugs, if the top tube was changed or it has housing guides, but no signs about them. I don't know. The tubes were in excellent conditions.
