Hamburger Aluminum Rear Sump Oil Pan - 360 Small Block

Wow, that's a freakin awesome piece of vintage MOPAR race art. I used Hamburger parts in the 70's, when was this pan built? I'm not drag racing so not a buyer but flag this for folks as a pennies on the dollar opportunity for your drag A-body. If anyone has a similar vintage road-race pan let me know!
