Alternator regulator needed

Hi guys, got an alternator that needs a new regulator but I cant for the life of me find one for sale anywhere!

The alternator part number is A127 AMR4247
I've added a pic of the regulator in question.

Cheers Mark

theres a place in Huddersfield that sells alternator and starter parts separately, somewhere I have a pdf catalogue from when I was looking for a rectifier.
cant remember the name of the place, and cant seem to find the pdf, and in the end I found a second hand alternator so never used the place!

not much help I know, but stuff is available out there!
if I find the info, i'll pop back ere'.

thanks, appreciated!
