[Tigers] Tiger's Girling Mk 2A Brake Servo

[Rob Hogan]

I called Moss Motors again and the knowledgeable person (Kelvin @
805-681-3411 Ext 7023) in CA described the 981-173 Lockheed Brake Servo
Booster as a 3:1 advantage unit typically used in the large Healeys, Jag
XK120 & MGC.  He described the servo as having the 7" dia. vacuum plenum
(as in the Girling Mk 2A) and is sourced from AP Braking in the UK, *not
China*.  A similar unit is reportedly available from Powertune, apparently
another UK source.  What isn't readily apparent is whether the mounting is
the same as the existing Tiger's.

Can any of the geometric or technical aspects be verified?
