I am no expert but wasn’t there lots of options available for a Paramount? So unless you have the build sheet how can you be sure what is “original”.
As others mentioned silver tubulars are the mostly likely choice �� but I think a nice box section clincher like the Sun CR 18 would look good and pretty correct on it.
