It was fitted by the previous owner stevie but I've got the engine build pics on a thumb drive I'll have a look.
My engine runs perfect very quiet and and doesn't smoke like fook even on the rollers at msd.
Even the shaft/spindle of the rotor that passes through the housing is worn, you can see different colours on it from shiny to dull, it's not scored just worn.
There was also zero debris in the sump I had a close look at it before I cleaned it out.
