The Hop Up: early LA hot-rodding

"Sleeping dog in Boyle Heights", Herman Schultheis, Schultheis Collection, Los Angeles Public Library. 

From David Conwill's piece at Hemmings. (and thanks to James Sorensen and Larry Cordell for the heads-up)
"...taken in 1938 by Herman Schultheis, a recent immigrant to LA from New York City and a doctor of mechanical and electrical engineering working for Disney. From the title and caption, it appears the LA Public Library may not fully appreciate what it shows: (A dog is sleeping on a littered dirt sidewalk next to a very old car parked on Estrada Street in Boyle Heights...)
"...It's an early hot rod—a gow job or hop up, as they were called at the time. At first blush, it appears to just be a stripped Ford Model T with later wheels, but certain features grab the eye and hint at its true nature..."
AL: see Clayton Paddison's period-correct 1926 Ford Gow Job on Kustomrama...

Note the parallel leaf springs above the sleeping dog's head. Art by Clayton Paddison.

Note the Ford crossmember and rear spring, the small brake drum inside the Model A wheel center, and the elongated differential housing indicative of a Ruckstell two-speed rear.
