Anyone got a BR Motorsport brake servo conversion?

I had BR Motorsport fit their bigger brake servo conversion back in 1988, I still have invoice but looking for more information if anyone has it.

I think my fluid reservoir might might be leaking a little and have no idea what parts they used for the conversion so I can get replacement bits if I need them. I have searched old posts and kevbrm might have had it in his car plus a post by someone called Wellard posted up a few years ago.

 

Hi Richard, 
If I remember correctly it was a Rover 213/216 servo and Austin metro master cylinder and reservoir. Made by ap Lockheed. 
Hope that helps. 
Regards,Kevin
