Nice find, Michelle!
You'll enjoy that machine. The PN5 would indicate it's a later model. The earlier ones came with the same PN4-A as the Olympia, but painted gray instead of chocolate brown. I agree with the others that a vinyl hose is a worthwhile addition and will improve its performance. The woven hoses are pretty but they're leakers, as we all know. I have upgraded both of my 1205's and my Super J with a vinyl hose. My Diamond J that I acquired from Goodwill about six months ago for $10 had one already. Enjoy!
