"Motorcycle, Solo (Harley-Davidson Model WLA)" by United States War Department is a technical manual written in the early 1940s. This manual serves as a comprehensive guide for the operation, maintenance, and minor repairs of the Harley-Davidson Model WLA motorcycle, which was used extensively during World War II. It covers everything from vehicle specifications and operating instructions to detailed maintenance procedures, making it invaluable for field mechanics and users.
