What source did the Pierce Arrow Company use for their cylinder block and other engine castings in the period of 1910-1920? I have read where Leland and Faulconer did work for Pierce Arrow but how long did this continue?
Leland and Faulkner made parts for bicycles- shaft drive gears up till 1900. I have never seen anything about them making parts for Pierce cars. They were known to specialize in gears, although they would make anything under contract.
The engines were cast at the Pierce-Arrow factory.
