Help with Creda cooker

Just had a phone call from my 300-mile distant 86 year old mother…

Turns out that the glass lamp cover in the oven of her Creda Concept Solar Plus cooker has just shattered. Problem is that she cleans the thing to death and ages ago the model and serial numbers disappeared off the label.

Looking at photos it looks like a 48319. Does anybody know if these light lenses/covers are reasonably generic (ie does the same one fit a lot of the range)?

I’d like to get one ordered for her and sort it out next weekend when I visit.

Thanks.
