Marklin steam battleship toy

Not sure on the year on this amazing toy steam boat I’m thinking 1930’s...I found this last month at an estate sale.. I didn’t know what company made it at first then found the mark on the rear rudder. a marklin toy! ...was amazed at the original in unplayed condition. The original owner was into steam toys and this was one of his childhood toys. This battleship uses steam.. water is pulled into the tank by heated boiler from a tube. once heated to steam, steam would burst out the next tube thrusting the boat down the water.. this toy is all original paint..
