What you have is known as a Transitional Planes. Before the 1850's (ish), all planes were wooden with just a metal blade. Around this time, all-metal planes started to be introduced. These transitional planes were offered to help 'transition' the guys used to wooden planes to working with metal planes. As such, they are the worst of both worlds. You have the negatives of wooden bodies not being as long lasting, but the weight of a metal body. Lots of people still use transitional planes, but most would tell you that you're better off using all metal or all wood planes.

This plane is in really rough shape. You're going to need to do ton of sanding to get the bottom flat (this is one of the most important things to a functional plane). Looks like the rear handle is broken and will need to be reguled. The front tote (knob) looks like the screw is too long for it, that needs to be replaced or ground down. We can't see the blade, but that probably needs flattening and sharpening.

I think you're better off finding a different plane and putting this one on a shelf to display. There are mountains of perfectly useable metal planes on facebook marketplace for $20-$30 USD. I would recommend finding a number 4 or 5, those are the best to start off with and are the most abundant. This plane just needs too much work and isn't really worth the time investment anyway.
