The HR case looks like a fair possibility to me, yes the rehaut is too deep, cgs are on the short side, but it could still work.
I tried to cut and paste from photobucket and ebay, but nothing works!
At any rate, with a good dial, hands, crown and insert and a drilling of the lugholes, I would think you'd have a decent 5513.
And the price isn't unfair, less than what you'd pay for an MBK, but with the MBK you'd get the crown, dial, hands and movement- whether you'd use them is another question.
So if you had the other parts and just needed the case, it might work out ok.
