Plane is about 7 3/4" long and the blade is about 2" in diameter. It weighs a bit over 2 lbs.
Has rust on iron parts and is missing a nut (under/behind) the blade, and has a crack on one side (iron part - see picture 3 closeup). Otherwise, has normal dings and wear, associated with age.
I could not find a maker name.
Appears to be really rare, despite the condition issues!
