Crossman reports the history of "Jos. H. H. Penton" in his summaries of American watch case makers. However, no records of this individual have been found outside of Crossman's account. However, Samuel H.H. Penton was an active casemaker in New York City during this era. Various records, known addresses, and an obituary for Samuel H.H. Penton published in 1900 correlates with Crossman's account of "Jos. H.H. Penton." Nieling's "Hisotry of the American Watch Case" carries this information as well, presumably sourced from Crossman.

Based on this evidence, it appears that Crossman incorrectly published Samuel's name as "Jos."

Samuel's obituary in the April 25, 1900 issue of The Jewelers' Circular-Weekly indicates he apprenticed under Bowman & Ebbitts and started his own company in 1858. He continued until he retired in 1894, selling the business to John R. Howard.

Advertisements indecate a "S.H.H. Penton" at 65 Nassau St. in 1870, the same address attributed by Crossman's summary.
