Having lived in a suberb of Philly for 64 years i was very familiar with the Sedgley name and knew a few people owning them.
They had employed quite a number of people over the years including a gunsmith by name of Martin Wurzer, and a stock man by name of Pete Peterson. They eventually formed their own business in Philly, and my father had several rifles built there looking very much like the gun pictured here, but without the schnobel forend.
