Here's another with blade fork.
So, the ones with blade fork match the catalogs from those years, which never show the Cruser 5 with chrome tube fork. Leads me to believe the chrome fork version was a special. Just looked at the '81 price list, and the order number CC5-6 is not listed, only CC5-5:

Not trying to start and argument, just interested to learn how these bikes came from the factory.
