This year we worked on this 1971 Schwinn Town & Country adult trike, which I bought for $100 from an old lady in Fulton who use to do her grocery shopping with it (Basket not pictured here).

It was a little dorky looking, and had thin wheels with annoying Schwinn non standard wheels. So after taking it completely apart, a deep cleaning, and a fresh lubrication, we adapted a springer fork on it, and rebuilt the wheels with some standard 24" 24h thick chrome rims imported from California. This allowed us to put standard white-wall balloon tires on it. We found the gear shifter cable from new old stock at the Cyclery on Erie Boulevard, still with its 1983 price tag on it! This was a two-years effort.
