Crank about to crack?

[jordic1968]

I've seen a lot of these stress cracks but never a broke there. What I've seen many times to break apart is the arm itself by the middle. It happened to me! Anyhow, it's a common bit so wise to replace it as adviced here

I've emailed Hillary incase he has the spare left Crank, but no response as yet. But yes would rather buy from a known seller of vintage parts.
