Dapol also do compatible one quite a bit cheaper. Your measurements puzzle me though. 'Standard' diameters are 12.6mm or 14.1mm. Yours are somewhere in between, so maybe you should measure them again. Remember that it's the tread diameters you are measuring, not the flanges.
Those 'bad' wheels as you call them definitely look like very old style width patterns so it doesn't surprise me that you are getting problems on points with those.
