It'll probably be an oil bath air cleaner, a paper element was optional but I've never seen one.

If the wire mesh element has a lot of hay/straw/rushes in it I usually set it on fire to clean it, don't forget to take the rubber sealing ring off if you do this.
Proof you need to have a few more joints in your hand to work on a David Brown, look at this chap's hand!!
