What kind of plane is this? Or is it a plane?

It’s probably called a corner plane. Irony.

Looks like it might be able to clean up a rabbet joint but thats about my best guess. Hope someone has fun with it

Otherwise known as a Core Box plane. used to make large cove moldings. These also had “wings” one could add on, in case the molding was a might deep. yep, it is for wood. Look up in the space between a wall and a ceiling, this plane type would have been used to help make crown moldings.

That’s one of those things that I’d be tempted to buy just because it looks so cool… BUt then it’d wind up sitting on a shelf and I’d never use it!

This is a Stanley #57 Core Box plane, with the extensions bolted on. One could do up to a 5” radious circle with this. Pattern maker type of plane.
