Just wondering about the history of this item. I recently was lucky enough to acquire one purely by accident. I went to a fella's house with a friend to pick up a 40 COE he had purchased and amongst all of the sellers "treasures" I spied this frame. Long story short, I managed to buy it for my 46 project. I have seen a couple before but very few and was wondering why they are seemingly so scarce.
Mine does need some repair (one hole drilled through the frame and extra holes added for the hinges need to be welded up) but I took a chance an offered him $150 for it and took it home. I don't know if that was good or bad, but it was worth it to me!
