I recently purchased a 1929 Chev Truck. I noticed there is no air cleaner attached to the RJH-08 Carburetor. I cannot find one on the internet anywhere. So, if there was one, I can fab one but I would like to know what was used inside the original air cleaner for filtering the air? Any info is greatly appreciated.
For Info purposes:
Block Stamping is 835501, E 6 9 (looks like May 6, 1929), has the Chevy Bowtie with 15 adjacent (??), Block serial number 675547 --other than the date on the block casting, I have no idea as to where the block was cast.
The 1929 carburetor did have an air cleaner with copper ribbon coated with oil. The ribbon is like a Chore Boy but instead of soap is coated with oil. The air cleaner has a tube from the crankcase vent at the back of the block for early engines or the oil fill tube for later engines. The air is taken in on the firewall side for 1929 air cleaners. I think I have '29 air cleaner but need to check to be sure.

Good explanation by Chipper. Here is a couple of pics of the air cleaner and pipe to oil fill on my 29.
Chip, If you do have an extra air filter, I would like to purchase it from you. Noticing the pictures from David (thanks Dave), I could replicate that filter if need be. As to the oiled ribbon, similar oiling process of squeezing out as much oil, low weight oil, from the ribbon, as I would have done with similar foam filters on 2 cycle air filter needs??
And yes, the oil filler tube has an open to atmosphere 90 degree inlet, roughly by eye, say 3/4". Again, open to atmosphere is typically not a good solution to any motor. Wouldn't this inlet have some sort of filtering to prevent water entry??
I call it copper gauze rather than ribbon. About all it filters out is bugs. I've changed my 38 and 53 to modern filter elements. A loss of points in judging but much better on the engine.

The picture posted above looks exactly like the "air cleaner" on my '29 sedan.
If you look closely, his has nothing inside of it.
Neither does mine.
It was essentially a centrifugal apparatus that really just kept out the rocks, and didn't do a very good job of that.
My uncle overhauled his '29 some time in the 1940's, and he and Dad and two others had never seen the mountains so they decided they would drive out to Banff to break in the engine.
Along the way the engine suddenly developed a bad knock that seemed to be coming from the upper end.
They had enough tools along so they pulled the head right there on the side of the road and removed a very small stone that had made it past that "air cleaner", and notched itself into the top of a piston.
My understanding is that the mesh was added in 1930, and was probably retrofitted to many '29's
