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

I have parts to a steam engine that I would like help identifying.  It is a vertical twin.  At first I thought it was a Stuart Double 10V, but it is to big.  It is almost 6" to the top of the cylinder flange, which would make the finished engine about 8" tall.  And the casting is not the same as the Stuart. 

Then I thought it might be a Tiny Power 2V-10, but they told me it is not.  They thought Stuart.

I "think" the four rods go with this frame, but I cannot be positive.  If anyone can help with the identification of this I would appreciate it.
