My favorite Marklin. This large flywheeled single cylinder is, in a way, the same in comparison of the 4158 like the Wilesco D28 and D32. With the 9cm dia. boiler and a valve to control the steam outlet, this machine just roars when placed under full steam. It is a stout but very well-balanced machine. Its rarity is a bit of pity, its a wonderful engine.
