I have a Hymer camp 55 1994, and have broken the small window (9 1/2" X 24 1/2") in the Luton above the cab. I priced the replacemant from Brownhills and got a quote of 436 British pounds plus VAT. I need a recycled unit. I think the following units have the same window 1992 - 94 Hymer models 51,52,55,56,64. Any help would be appreciated.
