I've bashed a lot of BEEPS - I just love 'em - I think I have about fifteen still, but only two unmodified: it's kinda hard to resist playing with them some. This is the most drastic bash. All new body and a Shay mechanism off to the size that works - crankshaft turns, pistons and valves actuate, etc. This Shay BEEP is called a SHEEP . . . . Its not a Baaaaahhhhd locomotive either.
My favorite though is this little Veranda turbine, which I called Porch Turbine, since a porch is really just a small veranda. This Porch Turbine BEEP is a PEEP!
