Circa 1960 Otto Cap used an interesting variation in his top-of-the-line bikes -- he brazed an elongated C-shaped piece of steel over an ornately carved stamped dropout, to give the appearance and thickness of a forged dropout. The extra thickness of a forged dropout or Cap's fake forged dropout arguably makes alignment more critical, but axle breakage less likely on a well-aligned frame, and it provides additional wiggle room in setting axle QR axle length.
