That style of bumber was commonly used on a lot of different cas and trucks, its the ach in the frame over the differenctial that tells me it has leaf springs. The large hud indicates touring car. Fron what I see I'm not going to venture a guess as to who made the car.
If I have a piston thats seized I know it's toast anyhow so I drill it full of holes to weaken it then break the aluminum out letting it fall into the oil pan. Cast iron pistons are much easier to get unstuck as the piston and block are made of similar metals so you do not get that horrible elctylisis working as you do with aluminum and cast iron.
I use penertrating oil, place a solid peice of brass on top on the piston then use the air chisel with a blunt chisel to set up vinbration to work the oil in, old wisconsin engines where you can remove the cyclder along with a seized piston I have made a steel plate with the same bolt patten as the cylinder head with a grease zek bolted onto the cylinder then pumped it full of grease.
Water generally comes in from the topside leaving the undeside of the piston and cylinder reasonably free of rust allowing easy removal of the piston through the bottomside. I would only try to salvage a piston if there were no replacements avaialable, otherwise go with an oversized new one.
A good machinist can turn out a new piston and rings, unfortuanely I'm not in that class.
