This cutaway Flathead engine is from a 1944 Harley Davidson WLA, one of Harley Davidson's military motorcycles. The funding from Harley Davidson's government contracts during World War II provided capital to improve engineering and design leading to the development of the Knucklehead and Panhead. #harleydavidsonnation #harleydavidsonnation #harley #harleyflathead #flathead #harleyhistory #bvmm #barbermuseum
