I stumbled into this. 

Look on page 230 for Newell info.

Interestingly enough, the catalog shows the IFS 84 was used on Country Coaches, Monacos, Foretravel, and some Prevost. 

I am going to do some investigation to see if Prevost has parts.

Now whether or not, you could actually buy parts is a different question. 

Here is a link for the patent  https://patentimages.storage.googleapis....783137.pdf
