The bike is a "Town & Country" by which name I've commented on the list several times over the years. 4130 Chrome-Moly frame, over-sized headset, very short wheelbase, heavy steering. Fun bikes, and I modernized several, including a triplet version. There are still some enthusiasts for the model.
This seems to be a repaint with some replacement parts, notably the fenders, saddles, and front stem. The chainguards look proper. I think the drum brake hubs are likely to be original, and the front is likely to be stamped as a Schwinn part.
I don't know the Schwinn family geneology, for that one should consult Richard Schwinn at Waterford. If you look closely at the right rear crank, it has the symbols A S & C O, which stands for Arnold, Schwinn, & Company. As I recall the story, Arnold was family name of the founding funder, and Ignatz was the Schwinn.
