Large lot of vintage legos - can you help identify some of the sets? 6270, 6990 obvious, rest not so much for me...

Any help identifying sets from these pieces would be greatly appreciated! I can see set 6270 (Forbidden Island Pirates) as well as 6990 (Monorail Transport System.) Does anyone recognize any of the others? I don't have these in front of me, just thinking of putting in an offer for the lot with only this info to go on.

Also in the same picture is a yellow corner wall piece that only came with 3 sets. 6259, 6276 and 1795... from the age of the other sets in the box I would guess either 6259 or 6276, with 6276 being the one you hope for.

Picture Lego5 has a sail from Caribbean Clipper 6274 in it.
