I can recognize a Waterford Paramount but I’m at a loss when it comes to knowing the difference between the various vintage P model Paramount bikes. I hope I'm using the correct nomenclature in describing these bikes. Is there an easy way to identify a P13 or P15? Do you have to physically see one to be able to recognize the differences?

Is there a resource (book) that explains which componets along with detailed information for restoring one of these bikes?

Thanks in advance.
