Older Corsair by Great Neck #4 Sized Bench Plane

Older Corsair by Great Neck. Maybe late 50's? #4 size bench plane. This is heavy casting and has a casted frog, so I guess this is maybe 50's.
I also think this may have been made by Sargent buy the way the frog is made, but again it's a guess. The Tote is cracked really bad and needs replaced. I have done nothing to this plane, it is how I got it. I bought out a large collection of planes recently and this is part of that bunch. Keep an eye on my listings as I will have about 50 planes that I will be listing over the next few weeks as well as some other items..
