Can someone please school me on 340 air cleaner

Here's a pic of the diverters. I'm in the process of restoring this one. I got the lid for this one off of one like I posted from ebay as the original was pretty beat. The Lower part was just like the 340 but only had one inlet. Somebody put another hole in it. Looked like they used a hatchet. Lol. If I can find it I'd be happy to give it to you. 20210102_104013.jpg
