Good to hear from you Gunny. I've been busy since I retired. I hope you're not telling us something, with trips to the cancer center. If so, I pray all goes well with you and yours. I knew about the police model. It is based on the 1849 Pocket frame. The problem was the .44 caliber version made by Uberti, as it was never anything but .36 originally.

"The New York City Police Department was established in 1845. At the time, New York City's population of 320,000 was served by an archaic force, consisting of one night watch, one hundred city marshals, thirty-one constables, and fifty-one police officers.

Under Mayor William Havemeyer, the NYPD was reorganized on May 13, 1845, with the city divided into three districts, with courts, magistrates, and clerks, and station houses set up.[3] The NYPD was closely modeled after the Metropolitan Police Service in London, which in turn used a military-like organizational structure, with rank and order.

In 1857, a new Metropolitan police force was established and the Municipal police abolished. The Metropolitan police bill consolidated the police in New York, Brooklyn, Staten Island, and Westchester County (which then included The Bronx), under a governor-appointed board of commissioners.[5] Mayor Fernando Wood and the Municipals, unwilling to be abolished, resisted for several months."

At some point in this process, Colt produced the Metropolitan Police Pistol, perhaps to ease the transition. Stay well, Gunny. Stan
