Strange bottom bracket

The shell is 68mm but i'm not too sure of the threading yet. I'm going to have a go at removing it tomorrow with the proper tool they make for this type of bb. If I can't find a cheap replacement the frame will have to go!

Don't bother trying to take it out mate. Just clean it up and put it back together with new 1/4" bearings. (11 on each side)
