Can anyone help me find out more about this hatch I recently received? I have some ideas but would like some feedback. These are my current thoughts: The hatch was found in Narva, Estonia. I believe it to be off a Russian lend-lease M4A2 Sherman. It was originally rusty but has since been cleaned up. Also, if you notice, the hinge still has metal pins within it. It looks as if the hatch was blown off the tank. There are also missing pieces from this hatch that look like they were removed with force. I'd love to hear your guys' thoughts.
