Single Oven Unbranded (Chorlton, Manchester M21)

Stainless steel finish unbranded oven.
This came from my sons apartment he just bought so is not tested or used by us as it was immediately replaced but does seem to be working fine.
No markings for switch positions, which is a pain but should be easy to figure out, and it’s pretty dirty.
It’s going to recycling unless anyone thinks they could use it cleaned up.
