I have always loved these movies and want to support this project however I can! I have various copies of the Australian HDTV airings of all three films, but only at 720p and the HDTV bitrate we're stuck with in Australia is notoriously bad, very rarely getting higher than 8mbps. All are 1440x1080 PAL and quite heavily watermarked but they are all direct copies straight off the TV antenna.
Jaws 2 and Jaws 3 are unfortunately cropped down from 2.35:1 to fit 1.78:1 with picture missing from both sides.
Jaws: The Revenge is 1.78:1 too but it's open matte, not cropped and the picture is miles better than the ugly Australian DVD. The shark kebab doesn't explode in this version and Jake doesn't surface.
I also have the two behind-the scenes TV specials for Jaws 3 and 4, freely available on Youtube in ULQ, and a LQ copy of Jaws 3d presented in red and blue 3D from some kind of Asian video disc. Importantly, this 3d copy still has the underwater tunnel green screens that made it into the final theatrical cut and the original VHS. They were digitally tinted light blue in every other copy I've seen.
I have a slow upload but if you'd like any video stats, screenshots or clips, please let me know!
