Was it common for them to have the intergrated seatpost clamp?. And what size exacltly are those tires?
Some companies used the integrated clamp as a means to save weight. It came and went depending on the year. Hutch had the integrated clamp for only one year (1983). JMC had it longer I think and also used it on their larger bikes. I do not believe Profile ever had it but I could be wrong.
The real skinny tires are sew-up, tubular tires. Self-enclosed, they ARE the tire and tube. They must be mounted to sew-up compatible rims. They are stretched and carefully rolled-onto the wheel and glued into place (so they don't roll right off when riding). If you are 6-ft, 240lbs like me, then you obviously do not plan to hop on and take it for a spin....so you can skip the glue. Just mount it dry. But if you are building it for your son to ride, then use glue!
Sew-up tires are not all that common, and are downright hard to find at times. Especially era-correct ones. Clement (super-rare and very cool), Panaracer, Comp V, and Cycle Pro (snakebelly) all made sew-up tires. For old school hoops, Araya is probably the most common. Italian-made Nisi rims are a great choice and lighter than Araya.
