Need help identifying diesel engine

Wow, seems to be quite unusual. http://www.modelenginenews.org/cardfile/speedDemon.html

Thank you all so very much that info helps a ton and I would like to believe this is a speed demon engine. It does very much resemble one almost to the tee. I have read about it on Adrian Duncan's review and that info along with the model engine news review helps solidify my confidence. I think I got a bit lucky scoring the relic of an engine and it will make a strong addition to my collection. Again thanks all for the help I couldn't have figured it out on my own.

Something out of a deluxe early fifties British prison workshop?

Yes, it sure does look like the Speed Demon linked to above. If so, my guess of the numbers being a date are not correct either then.

No problem i appreciate the help regardless. I'm just happy i figured out what it is and thankful it's in functional condition.

Well, the one in the link has the number 1255. The MEN review states date unknown, so I'm supporting the date theory.

I will not oppose any theory or opinion by any means since all stated in this post are valid (based on information from MEN and other forums). Even if the 4 digit number on the back of the engine was in fact a date of manufacture I'd still be pleased the engine is as close to the speed demon as it sits now. I have always loved the model diesel engines made way back when that still live in this day and age. It will live in my display case for many many more years and live a happy "uncertain origin" life .
