Looks nice, and running strong.
A very nice plant you have there

Well done and thanks for sharing!
Looks good running - is that a Stuart D10?
It’s not a Stuart and I don’t see any markings on it. I thought it might be a cheddar but I have not seen any cheddar pictures that look like it
The engine is about 6” tall, 4 3/4” long and 2” wide
