This doesn't look quite like the one on my 1957 Aceca Bristol (BE588) which is the same as on a 1962 Aceca Bristol I also owned. (BE817), These also have a Bristol 'bent' head spanner and a Bristol plug spanner and a wheel hammer, otherwise it's similar (presumably it's for an AC engine car but don't know why it wouldn't have the wheel hammer). The Garrington spanners are correct; you also have a space for pliers, screwdriver, brake adjuster and a rod of unknown use. I do have some photos of my tray somewhere on the computer but can't find them at present - I could take some more if useful. There was also another thread about 2014 from a chap with a replica who was making a copy tool tray but, again, I can't seem to locate it.
