I contacted a man from Navistar several years ago about an Original they had. I was thinking it might be 501 or 590. He was kind enough to have some guys take it out of the crate, check the serial# and take a couple photos. I think it's the same one from the photo at 401 N. Michigan Ave. I have since lost the emails but I'm pretty sure the s/n# was 29409. I still have the photos. I believe it's in a warehouse in the Chicago area and they may also have the 149.
