It was clear that there never had been one fitted because the lugs on the grille which are melted to hold the guide in place were pristine.
I was just wondering whether the guide was an afterthought and if so, what was the problem which made it necessary?
Any info please?
Also, what is the best way to polish tarnish off the chrome please? The inner edges of the vanes seem to have some muck on them which wasn't susceptible to the soap and water I tried, not wanting to try anything more aggressive without guidance.
I know this second question should be elsewhere but I thought to save the number of posts
