The neat thing about this little Pacific is she's actually an old friend of Maine Two Foot Fans. If you happen to have a Pre-Jones edition of Maine Two Footers and look in the back under "Two Footers from other parts of the World", her Baldwin builder's photo is there.
When I saw these pictures in the mid 70s as a teenager I wouldn't ever have guessed this engine would still be around then, never mind today.
She's a pretty substantial little engine, actually quite a bit bigger than SR&RL #23. I have a feeling she would have been way more engine than our own two footers could ever find useful.
