The P-1H was a 1932 variant of the Parks P-1/P-2, reverting to the P-1 designation perhaps because it was an entry-level model with a 100-hp Kinner K-5 radial. Dean Hammond of Ann Arbor, Michigan purchased the rights from the bankrupt Detroit Aircraft holding, and the designation officially changed to Hammond 100 as of January 1933. Seven examples were reportedly built, of which N15771 (c/n 204) was still airworthy in 2022. Photo from: Dan Shumaker collection
