There may be a small spot where it goes all the way through. I haven't taken the brush to it yet to know for sure, but at first glance - what do you think? I realize that this frame is 71 years old, but being DB 531 its a really great rider and I want to keep it for the long haul. My plan was to someday send it "home" to Mercian in the UK for a full resto and enamel job. Anyway, that's not in the cards just yet.

Thanks.

Get it all cleaned out and see how bad it is, if its all the way through then it may be time for a creative cutout, rust convertor, paint/seal, frame saver throughout and the sealed BB.
