Looking for 1.2 sump part number?

I've had an advisory on my MOT that the sump should be replaced due to rust, so I'll just change it.

There are a few different shaped sumps on ebay for the K12 1.2, is there more than one engine type for the 1.2?
Does anyone have the nissan part number for the sump and sump gasket that I can use in the search for one.
