A good while back, I decided to rebuild my Girling servo and was unable to complete the task when I found a crack in one of the unavailable air valves. I replaced the Girling with a Lockheed unit and easily designed brackets to mount the unit onto the same studs holding the Girling. Over the next year I used the Lockheed unit but was able to source a new air valve from British Car Specialists out of California and finish the rebuild of the Girling servo. Although the Lockheed worked well, I found it actually produced less assist than the Girling and I eventually switched back with the Lockheed as my spare.
A friend was thinking of boosting the brakes in his BN6 and told about the PBRVH40 (https://www.hydroboost.com.au/boostertypes.htm) by a Healey enthusiast out of Hong Kong. A smaller Lockheed look-a-like, the unit used by the Hong Kong Healey owner was purchased on eBay and supplied out of Australia. According to his recommendation, of the 2 single-line models available (VH40, VH44), the VH40 provides a higher brake boost although the VH44 was often used in place of the Lockheed on disk brake equipped vehicles. Since I found the Lockheed to provide less boost than the Girling and understand the VH40 produces quite a bit more boost than the VH44, I thought this could be a better alternative for those looking to replace their original Girling servo...
Although I have no experience with these units, I though I would pass on their existence and maybe another forum member can provide additional information.
All the best,
