Identifying Correct Ring Order on Compressor Piston

[Burgerkong]

Silly old me didn't take enough pictures when taking the pump apart for its rebuild, now I can't seem to remember if the wipers/rails go below or above the scraper rings in the top two grooves. I have a set of scrapers that I took out for the oil control spacer (ziptied to the ring bundle), but there are two thin wipers still in the ring lands that I didn't remove.

Note to self, take MORE PICTURES.

top ring has rounded edges, 2nd is alot squarer, 3rd is the carboard weave with top and bottom rings for the scraper
