Who’s got a picture of the right grooves ?

Henk, while that might seem catastrophic, the bigger thing to check is to make sure the well was cut at the parting lines first. FWIW, many engines with cast bearings during that era did not use oil transfer grooves.
Personally I use the KR Wilson groove cutters which automatically cut using the cap bolt holes as the datum. I have included two segments of factory prints on a PDF below that will show you the basics of how they should look. Hopefully this will help you.
