Hi, we tend to think of metallurgy problems only affected the Colt Walker. No so, the book documents a number of Paterson cylinder and barrel failures. One military command even withdrew use of the Patterson reporting a number of problems.
Most of the problems occurred from Patersons manufactured by Ehlers during the Colt bankruptcy where inventory parts were assembled, some with different serial number parts. Seems there was little if any quality control.
It amazed me to see a plate of a Patterson with serial number 1 that is a .54 caliber revolver.
