Maybe the metal foot/leg rest piece is stashed away somewhere? It would help a lot if the stroller had all it's parts, since the chrome is still in good shape. If you can find that metal part I'd get all the pieces attached right, vinyl upholstery cleaned up, and offer it on ebay. Even if the foot rest is lost someone might need a replacement seat, hood, tray, or even a better frame for theirs and will bid on it. I'd try that before just scrapping it altogether. Try the walker too for that matter. You never know with ebay buyers. getting a little something for them is better than scrapping and they are fairly easy to pack up and mail.
