The Silver Ghost used Reynolds 531, plain gauge, main tubes with high tensile forks and stays. All the ones I'ver seen (and owned) have had stamped dropouts. It was 2nd in the line and originally designed as a club racer, being spec'd with tubular tires for 1973-1975. In 1976 it was downgraded to clinchers but was otherwise unchanged. There was a major makeover in the livery for its final year, 1977, when it became CCM's top model.
It's not valuable but is fairly rare, particularly if it is a tubular tired model. Very few of these survive, with the original wheelsets. Most got changed out by frustrated owners.
