*Very* Rare Part... I'm out at $1200

Interesting fact.  

 

My late series 1 has a attachment for the hand throttle on the pedal, but doesn't have the mount for the cable.

Visual proof that your Hoover sucks.   ?

I too have the series-1 choke/throttle mechanism with cables...   however, my throttle knob is cracked at the base. A clean crack not immediately noticed but - a crack nonetheless. 

Any repair tips, and or, suggestions?

Crazy glue.

Yea, super glue clamped.

Hi Blue , I am happy you use my pictures.

Here are some for you , I want to explain again the difference , and interchangeability of the mechanism . 
 

Z432 ( triple carburetors) has only one cable for the choke system while L20/24 ( SU) have two cables . 
 

But you see the basement of the levers are made for both , just flip it over to accommodate Z432 or L20/24 . 
 

And some more , the earliest Z432 mechanism has a metal tube for the choke cable . Like SU type cable , Z432 has a lot of running parts change for this choke and throttle mechanism.

Not only for the cable , levers were revised a several times .
The earliest hand throttle lever has its pivot at the bottom of the basement while later type has the pivot in the middle.A  Sliding nut guide which controls its tension is a unique for the earliest one. The  earliest one has a longer slit on the top metal face plate so that the hand throttle lever can travel fully, longer . 
And amazingly,  the small screw holes to secure the basement for the earliest one are used agin for the later hand throttle!! 
 

What a wonderful design of mechanism .

Sorry those pictures are not taken at one time , some of them are recently and some of them are old . I found the two pictures which showing Z432 and L20/24 in one shot made a mistake, the top metal face plates were put wrongly. The longer slit of the hand throttle should be put on the other . In this picture the L20/24 mechanism should have it as it is made as later type .

Very clever engineering!  Just like the rear control arms. Thanks @kats
