Thomas, yes, you have the Alpine version of the Suntour Perfect. It would have originally had a chain guard that uses a cir-clip to attach to the retaining ring/outside bearing race above the smallest sprocket. I might have one but it is not really needed when the RD is adjusted correctly.
Everything else is the same as a 5-speed Perfect or ProCompe. The two smallest sprockets thread on and the three largest sprockets have the typical four-tab of the Suntour A sprockets which also fits on the Winner, Accushift, Alpha bodies.

Jon, if you need a 38T low gear, I have a 6-speed Ultra spaced Perfect or ProCompe available. PM or email me if you are interested.
