I don't know much about this engine or the maker. I don't know what the model number is except that I've been advised that it's 80-82 depending on size. Going by what other people have said about similar engines, I think it was made c1910.
The engine is a simple but elegant overtype. It has a brass boiler, 50mm diameter x 130mm long. The original burner is missing so I'm using an SEL two wick burner. Boiler fittings consist of a whistle, safety valve and dummy chimney. Steam is fed directly through a short steam pipe to the back of the port face of a single acting oscillating cylinder. The cylinder bore is 7mm and stroke 20mm. Exhaust exits directly from the port face to the atmosphere. The engine bracket, port face and crankshaft bearings are all pressed from one brass piece, which is soldered on to the boiler. The crankshaft is a simple bent wire, with the crank at one end and a 57mm diameter flywheel at the other. I'm not sure what the flywheel is made of. It looks like either nickel plated brass or stainless steel; neither of which are consistent with the rest of the engine, which is mainly brass. The whole is mounted on a wooden base, fixed by a rather crude modern looking threaded rod. This engine appears to have been much restored in the past and I'm not sure what parts are original (if any!). The whistle is definitely a new replica. The base is almost certainly new. The flywheel doesn't look right so I assume that is a replacement. The chimney looks newer than the rest of it, but could just be well polished. When first steamed, there was a serious leak at the bush holding the whistle. I have resoldered this and it's now ok.| Make | Fritz Neumeyer |
