Schwinn 24 bike Frame Middleweight Cantilever Bicycle vintage pre 63 L Lowrider

  
Frame as shown fits 24 wheel set. Serial number single letter "L" indicating pre 63?

Sew pictures of kickstand tube for what looks like a repair to the fender bracket. These 24's can be fitted with a 26 wheel set if you grind the rear drop out some and install the rear wheel with the tire and tube deflated. It's kinda sorta like a donked out bike in a way and I have done it!

The ride is smooth with a bent 26 fork set up.
