Hi Tom, just my guess, but it may be a stud attached to what appears to be a simple cap. The "cap" may actually be achieving some clearance setting inside the oil pump for good performance. So as a precaution you should have a good photo of this cap for reassembly reference (you already have shown this), and maybe even a match mark for return to where it was (or close).
The fitting coming out the bottom might be a stud as part of that particular gear shaft, that can be locked to keep the "cap" clearance setting.
As i said, just a guess, others please jump in and save the day here.
You can clean this externally with spray on paint remover, work in the remover with throw away brushes, then clean away with spray carb cleaner. Just make sure to do this outside, with face and hand protection and make sure all the clean up paper stays outside. spray paint remover will remove paint on cars and house as it waffs around in the wind. So find a big throw away cardboard box to contain this in.
