hard & soft top questions

["Evangelos G. Makris" <emakris@hol.gr>]

My hardtop is made by "Denis Ferranti Laminations Ltd"
and my softop by "Coventry Hood", batch # 2995, part # FS216.

Since I may need to replace or find parts for either and 
a net-search using hotbot and altavista showed no relevant
matches, can you please tell me if those people are still 
in business, how may I contact them or where should I 
look for parts and replacement hoods for my 1966 HAN8 MkIII
Sprite?
