In heated storage for decades before being acquired by its current collector owner, and displayed in his collection since.  Chain drive, single cylinder engine.  Engine has compression and turns over.  This Crestmobile has not been traded publicly in over 40 years.  Rear lamp not shown but included.

Built locally by Crest ManufacturingCompany in Cambridge, MA.

Wonderful patina, and a very reasonable London to Brighten candidate!
