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.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.
