Well Ryan came home today with 2 things for me. First one is a Blue Royal Model 880. Needs a new belt but otherwise works great. The second one is a Hoover model 29 S/N is A5249662, with the orig. Hoover dump bag. So if anyone can give any info on a manufacture date, or anything else. They were sitting in a basement of a customer of his, so they are pretty dirty and both bags were pretty full of who knows what. They have service stickers so it looks like they were well taken care of. Pics to follow, im going to clean them up a bit..
