Classic/vintage wheel question

shinytop

I'm after a couple of press on hub caps like the one in the picture for my trailer.  One got lost and the other is looking a bit worse for wear (mind you so is the wheel!)  They are 13 inch wheels with 4 holes and 4 inches between centres.  The cap is about 9 inches across depending on how it is measured.  The wheel has 3 flat sections that the inside rim of the cap presses (or is more likely kicked) onto.  I acquired the trailer years ago and was told it was originally a small caravan.  I have no idea of the origin of the wheels.  Any ideas?

Well it was the  UK Holday forum or Motoring? For your post? LOL

So close enough, looks like Morris Minor wheels?

Look on Ebay plenty stating 9" dia etc.

Oops, don't know how that happened, don't think I've ever been in this section before!  I'll try again in Motoring but thanks for the reply!
