Just dug out some old catalogues and your Grand Hotel Courtesy Car Brighton 77 could be DG14 004a (brown body cream chassis) or DG14 004b (brown body beige chassis); both of which are 1934 Model A Fords with hood.
Lledo are now a part of the corgi group. I used wo work in a distribution warehouse that handled them, kany items still in Lledo cartons. My only suggestion is an enquiry on the corgi website. hope this is of some use to you.
