All, Here's an update while checking emails I received this Drawing of a ALCO 433-H , short paragraph on Man / ALCO G 3300 BB 4 AXLE Locomotive. Please see Photo and link in my original post ! The C433-H is a proposed four axle counterpart to the unbuilt C650-H, almost nothing is known about this unit, only having a part of a blueprint and a designation. Tom
