This engine was actually a "P&LE" note the P&LE on call bin and then NYC SUB (The Title Giant) engine). After WWII the P&LE was ready to sign a contract for DIESELs. When NYC top management forced them to order ten of these from ALCO. Based on what all happened after 7 were delived P&LE Management canceled the contract!
The things you referred to as values on the side of the fire box were actually part of the "smoke-consuming equipment."
