Another “ID my A833” thread

What diameter is the front bearing retainer? Is any of the case aluminum? What is all of the info stamped on this pad on the side? Get a magnifying glass and a wire brush.

I was told it’s all-aluminum and definitely an OD with the bigger bearing retainer. He’s got other parts for me, so I’ll be able to see it in-person. This fortunately isn’t an item needing to be shipped.
The case numbers he gave me appear to be more like serial numbers…66(or GG)182453.
