I've got a 1275 cross drilled S crank that I took out of an S block some years ago. I think it is a mk3 S crank, but it does not have any of the usual markings on. I would be grateful if somebody can shed some light on this, pictuyres are below

It's pretty tough to read anything off that. In fact I don't think any of those numbers can be read clearly enough to identify it. None of them seem to be part of a Cooper S crank forging or part number.

I'm with you on that. It is an S crank, I'm pretty sure of that, but have never seen one like it before. The reason I am pretty sure it is an S crank is down to the factory style cross drilling, which seems to be at 120 degrees, with the factory style brass reducing plugs.
