Do some research on retro bike, it was a thing. I bought it as a project but not enough time and this one really is a big project. These frames have a habit of braking the bonds between the glued tubes and lugs. The paint on the lugs are one sneeze away from fully going, as the alloy has oxidised underneath the paint. It only has one brake mount so will need ro source or make one. The main linkage between shock and rear stays is missing so again, source or make. Everything is rusted or oxidised. Seat post isn’t seized luckily. The bb present seems good but I dare try to take it out, I think it holds the chain stays in place as it pivots here. A big project but only if you’re brave. Not for me, I’ve got a house that needs rebuilding you know how it is. They do look very nice when fully built up, last picture is obviously for inspiration and is nothing to do with me.
