Hello all, Have had these in my tool cabinet for a long time, don't remember ever using them although we did have them on a set-up we made that was never finished. these are 2 ARO #129121-920 filter and regulator. white filter part is still clean, one of them has some marks on the bowl cover but hey do not harm the function, maybe just shelf marks or storage marks.
