This engine is pretty basic and surprisingly small. It has many similarities in style with Wilesco and, I beleive, there are (or were) connections between the two companies. The name Fleischmann is not marked anywhere on the engine but there is a label which says "Wilfried Boecker, Motoren & Luftpresser, Schwitten" in fancy Gothic script. I assume this is probably a retailer's ID.
The boiler is 38mm diameter x 97mm long. The burner is a simple Esbit type but I don't think it's original. The boiler fittings consist of a whistle, a steam feed pipe and a safety valve. The original safety valve is missing but a Wilesco one fits. As received, it was fitted with an air connection. The steam feed goes directly to the back of the cylinder port face.
The cylinder is a single acting oscillating type, 6.8mm bore x 20mm stroke. The piston is connected to a simple crank on the end of the crankshaft, which is supported by two pressed steel brackets with a 52mm diameter Mazac flywheel between them. There is a pulley built into the flywheel.
The base is pressed steel and the base mounted chimney is a cosmetic dummy.
The paintwork is not original. The safety valve bush has been replaced and fitted with a standard Wilesco SV. The burner does not appear to be original. As acquired, the whistle valve was loose and would not hold in the closed position. This was an easy repair, necessary before I could test it. Other than that, I have not yet done any work on it, although I might restore it to something closer to original at some time.
