Can anyone tell me anything about a block plane with the numbers 306-16 cast in it? It resembles a Stanley 60 1/2, but it is wider, heavier, and some parts seem to painted grey rather than the typical black. I wasn't able to find a manufacturer's name anywhere on it.
I tried searching for this model, and I can't seem to find anything on it.
I don't have any pictures yet, but will try to get some soon.
