Beautiful boat!  What is the size and type of engine! Oscillator?

It's a Wilesco engine, but not one of their standard marine engines.  It is an oscillator, which you can see if you follow the link above the picture. The boiler is probably the same size as in the D48, but I haven't measured it.  The boat is fairly large -- a little over 2 feet long.
