So, I don't know if there's a crack in the steel under the chrome, but there is definitely a hole there... Not sure what this means in terms of cause, but I guess I would need to get rid of the rest of the chrome to see the whole problem.

When I recieved the frame I noticed that I could flip the frame over slowly and it'd sound like a rain stick. I thought this was brazing material in the frame, but maybe it has to do with this? Anyway, I don't know what my options are at this point to make the frame usable.
