I think the oval badge on the front center of the base looks like Doll (DC), though E. Plank and J. Falk also used an oval emblem. Fleischmann was the follow on from Doll, so there is often much similarity evident! The engine itself and the pedestal it sits on both look very much like a Fleischmann configuration, but the firebox under the boiler and the chimney do not. Chimneys are often not original to any given engine. If it is a Doll, it would likely be very late production shortly before Fleischmann took over the line.
