Dolmar 133 filter types

[BraveSirRobbin]

Hi I'm new to the forum, and to dolmar chainsaws. Last week a purchased an old dolmar 133 , it has a single flat filter on it with a single center knob for the cover. Most of the on line pictures show a two piece filter. It's also the only filters I see on eBay. So my question is, is this the proper filter, and how many different filters were there for the 133?

Looks like the parts list from 12/1983 could be useful.
Item 9 could be that single layer Nylon filter with single hole.
