I just got an original oil bath air cleaner for my 54, which did not have one when I got it. Upon opening it to clean it, the inside appears stuffed with a horsehair like material, looks sorta like wood shavings. Is that supposed to be there, or was that the work of the critter who also deposited some dog food nuggets in there? Theres no oil residue in there, either. Sure looks good though...
