Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

  Well, it does look cool. 

  I too have picked up several unidentified
engines.  Must be because they were not
very expensive.  I have a thread on this
site asking for ID with my engine.  Too nice,
I think, to be a complete home design/cast/build.

  As to the bore/stroke dimensions.  The stroke
ought to be easy to measure.  Then, you could
make a reasonable guess at the bore by measuring
the cylinder diameter and guessing the bore down
from there.  I'd really like to know.

Good Luck,
Wayne
