Antique american flyer set wide gauge/box works

Here is a very nice wide guage american flyer set,box is in poor shape and can not read set number,has 8 curve and 4 straight track with conector and transformer,tested and works,the one conector is loose on transformer but still gets power to track and train runs smooth both directions,the pin to connect tender is missing,chain is there,all wheels appear original,one drive wheel has some chipping(does not affect running,but front leading truck has some bad chipping and wheels should probably be fixed(mainly one).All cars in great shape except caboose rear roof had been bent at some point and has some paint missing where it was bent,has a small building and a warning sign.Please enlarge pics and ask questions if needed,THANKS!!
