Seen one of these?

I posted this pic last year, but it turned out to be the end of a thread.

Has anyone seen one of these carb link plates on a Doly?
It's equivalent to TR7 part TKC1718, but it's wider between the carbs to fit the Sprint manifold.

Got any more pics from other angles? Is it a shared casting to balance airflow from both sides of manifold? Does the servo pipe attach to it (cant tell from the angle)

Never seen one.
Guessing TR7 Sprint only?

Nope.
Having looked up what TKC1718 is, isn't it just there for somewhere to mount the switch that turns the aircon off at full throttle? I don't think aircon was ever an option on a dolly was it?

I think the other way round. My fuel injected tr7 throttle linkage had a solenoid to raise the idle rev a bit when the airco was on. This feature was very usefull on my car when having all the (6) 130w spotlights on.

I though it was just a pressed plate that held the two carbs square to one another, but it might mount somthing on one of the versions of the 7 that might have been an option for the TR7 Sprint, had it been put into production.

I think the other way round.

I think you're right, I was going from looking at parts book diagrams and asking google what all the bits on them were

UKC3741 appears to be what those two holes are the mounting point for and I can't see any other purpose for that plate. this claims it's a switch to cut the compressor and WOT, everything else in the world seems to agree with you though so I'm guessing the part number on that document is wrong

According to a Wedgista on the TR7 Forum, "On A/C cars the switch in the diagram senses full throttle (usually used in passing) and turns the A/C off for maximum power. It's on FI cars as well (but on the throttle assembly) with the solenoid which as stated ups the idle when A/C is on."

I'm still not convinced BL had a serious intent in 77-8 to produce the TR7 Sprint. That's because they couldn't have sold them in the US, which is where the 7&8 were very squarely aimed - look at the gap between release in the US and UK for the 7: the 8 never being really available. I think they may have considered it as an alternative/option to the TR7V8/TR8 in Europe, which may be why most of the prototypes (ACH/4 to ACH/25) appear to have been LHDs. But I think what Neil Eason-Gibson at the RAC said about a "promise to manufacture", as part of Bill Price's claims when homologating the 16 valve rally cars, that it was an option on the TR7, plays a significant part in why any of them were made.
