Princess mid-1990's bathroom fittings

[Simon 420]

The chrome finish on the toilet brush holders and toothpaste holders on our 1997 Princess 420 is now pretty awful. Took one apart at the weekend and discovered that "chrome" is a plastic part which has been sprayed / coated. The coating is now pitting and falling off. So its time for replacement

Does anybody know what make these are/would have been please?

What ever make / model they are, I suspect discontinued now. In the past I have taken the old fitting with me as I tour diy outlets and caravan shops trying to get something the same size that will also cover existing screw holes and marks.
