Hello 2Mk2,
The lever I have also has KW on  the underside.
However not sure if this is the brand of the sunroof manufacturer, or the manufacturer of the lever itself.
My sunroof panel is being treated in acid to remove the surface rust at the moment. When completed I will undercoat and fit the seals and post a photo to show placement.
The sunroof is definitely a Ford fitment to this vehicle, not after market.   

Hi Peter,
 
How's your your restoration going on the factory sunroof RS? I'm progressing on mine but not overly sure about the sunroof rubber seal though. By the looks of yours its riveted around the back where it's not attached via pinch weld. Mine doesn't have any holes around this section so not sure what is technically the original way to go. Any thoughts?
 
Cheers,
 
Adil

Hello Adil,
 
Long hard slow process at this end. I am sure you know the story. 
 
Not much progress on the sunroof but lot's of hours going into repairing it.
A few days ago trial fitted the sunroof pan back into the car. Now removed again ready for a nice coat of 2 pack Midnight Blue and then permanently fitting. The small holes in the underside of the pan are for 3mm stainless steel screws to hold the sunroof guides in place. This way there is no welding so the paint remains intact, and no rusting. I don't like making mods however can't stand the thought of bare sheet metal in a water course area. Also the guides will be removable without removing the entire pan from the car if fudge factor is needed later on.
 
I will need to check up on the riveting of the seal in place. Can't reliably remember.
 
Still unable to identify the manufacturer of these sunroofs. Latest lead is Skytop, however not confirmed.
 
 

Nailed it!
 
I have been speaking to the owner of one of the sun roof fitting companies. He is very passionate to find the branding and origin of these sunroofs.
A series of emails between us over the past few days and help from one of his old mates have resolved the question.
 
On the underside of the lever there is marking "KW" (no other markings).
Google searches reveal nothing.
 
However now appears "KW" stands for Karosseriwerke Weinsberg.
Google searches reveal the company and the origin of the sun roof.
 
Quote from email:
“Well you have nailed it. I did have K something in my head but KW is definitely the one , the name Pollackuckle Head  could be and I am not sure until another mate of mine gets back to me may have the answer . He used to run a sunroof business up on the north shore [Sydney] called Auto  Sun and Air it was part of the Bill Buckle auto group so maybe the Pollackuckle Head could be some sort of cryptic thing as they had some involvement back in those days with KW . I cannot find any reference on the net but my mate may have a clue when he gets back to me.”
 
Quote from email from his friend:
“They were the factory sunroof fitted to Lancia and Alfas back in the 1980;s. Manufactured in Germany by Karosseriwerke Weinsberg, Auto Sun & Air imported them for aftermarket fitment. Manual ones came in 2 sizes, and were slightly different in the way you remove the roof panel ."
 
 

Hello Adil,
 
Attached is a piccie of the sun roof panel showing position of holes to locate the seal.
 

Well done Peter. Looks like we might be closer to getting a little more detail on these things.
 
There are actually part numbers I have found but only on the nylon blocks for the runners. There a three pairs (Left and Right). Attached is a picture showing one of the nylon blocks and the part number. The part number in the picture is KW8973939L and the opposite side block is KW8973940R. This might help identify the exact model sunroof used in the Escorts.
 
Thanks Whooligan for your help as well, much appreciated.
 

 
Cheers,
 
Adil

I have an old pop up sun roof does anyone know a good sunroof place in Sydney to get it replaced.
