Replacement feet for old chrome bumper gear.

Hi, new to the forum but not to Naim gear and this is my first post. Got my first Linn/Naim setup in 1979 comprising lp12-Ittok-asak-nac32-nap160-kans mk1 from Russ Andrews in Edinburgh and was smitten by the Ivor ideology, being a young engineering student it made complete sense to me that everything at the front-end should be the best engineered, then I got married and had many children so my beloved hardware had to go. Now said children have flown the nest I am now getting back into listening and have got most of the gear I once owned. First question I would like to put to you guys is pretty basic but this is one of many questions. Where can I source replacement feet for my CB 32.5, Hicap and a old Snaps that are showing signs of wear/damage.
