This is a new very high quality and very correct oil bath air filter. This is very correct for the CJ2A and early CJ3A and has the three vents on the back side. It is almost the same as the WWII MB and GPW air filters but does not have the molded in instructions. The same goes for the M38 but it had a pre-cleaner or mushroom and there were no vents on the back side. This fits the original brackets just fine on all the models listed. The lower pan has the oil level markings. Just like the originals you can remove the inner element to clean. These are always missing or rusted out on the bottom.
