Just see this on E-bay , set of 2" carbs and manifold at £2100 , I did not know Coombs put there name on things 
£2,100? 
WOW! Is it autographed by the Queen 
? That’s a pretty high price for an XK140 manifold, a couple of HD-8’s and about 10 minutes of grinder hand work.
E Type 4.2 tri carb manifolds without Carbs go for $1500.00
And that took far more than 10 minutes to polish .
Rebuilt carbs? Definitely new throttle shafts.
He will probably get the money…
