Eric,
I have wondered about the history of this badly pitted frame.
I don't think frames are particularly prone to corrosion pitting, which is what this is.

A friend and I surmised that this one must have come from a submarine sunk of our coast(NC). It came ashore with a German sailor and was buried, or lost in the surf for years.

I once owned a T 2 Japanese rifle that had been "lost" in hurricane Ivan. A few years later it was dug up during a beach replenishment operation , pitting was a lot like this frame.
