Thanks Yobarr i reckon your right, the van it is in is a 1987 Windsor windcheater pop top. My youngest son whom has a caravan repair business in Perth and done 13yrs at Coromal ( only job he ever had ) before going alone 3 yrs ago, tells me it is the original. That's good for a 30yr old fridge and it's still working fine.
Regards Ge
PS: The 30 yr old van is a goodie to with original W.A plates.
