I have a frame with the numbers on the bottom bracket of A22804 and then parallel with the frame the number 553 . I've never seen two sets of numbers before. Sorry about no picture I haven't figured that out yet.
Not much to go on, but I suspect the 2nd set of numbers may be a catalogue number perhaps. Id suspect as just a guess that it MAY be a Huffy, AMF or Columbia build. Get picts if you can.
This could absolutely be anything. Many bottom brackets have a second set of numbers that were likely for use in-house to identify them on the shelf. Easiest hosting site you don't need to sign up for is IMGur.com--just drag a photo onto the site, then copy the
