tanks

Need help with years and rough value of these bikes, couldn't find a good serial number lookup tool. I'll get some more close ups when I get them cleaned up but I figured this would get it started. 1) Gambles Hiawatha - no horn in tank 2) western flyer sonic flyer - tanks with lights Thanks!

Stumbled across a red Schwinn Deluxe American of unknown vintage in the wilds of Indiana this past weekend, sans headlight, horn, and any racks, but with the original "Slimline" tank attached. Condition is maybe a 4/10 - not rideable, but not earthworm fodder, yet. What I'm interested in knowing...
