Tim:
I have the one in the below video. It cannot be steamed due to the end being covered in a tar material to plug the sight glass. Other than that issue, it is in good running order with the original burner.
I measured mine:
Base: 7 1/2" x 5"
Flywheel: 3"
Boiler: 7 1/2"
Total Length with Boiler and End Cap for Chimney: 8 3/4"
Total Height to Top of Chimney: 10 1/2"
