I have dealt with OOTB Outoftheboxmodels, they are a canadian outfit and I have paid for and received an ATSF shell stl and decals. After you pay , maybe a day or two you get a link to download the stl, I also got decals and they took a while to arrive but I do live near the bottom of the world! I found them to be good to deal with and am planning more purchases in the future
