3 Tamron Adaptall-II Canon FD mount adapters, two chrome, one black, three rear caps and one rare front cap
Canon FD-T-mount adapter
Canon FD-55mm reverse mount adapter with 52-55mm step-up ring, so it works with most FD lenses for macrophotography.
Vivitar Canon FD telescope adapter TLA-1 with caps and case--This is an eyepiece with an FD mount for turning any FD lens into a telescope. I don't know powerful the magnifier is, but even on a 50mm lens it makes a pretty decent monocular. It has some noticeable pincushion distortion, so I wouldn't recommend it for long viewing sessions, but for occasional use or spotting in the field, it's a handy little gadget.
I've consolidated my Canon FD setup, so these have been sitting on the shelf and can move on for cheap.
$25 incl. US domestic shipping, $30 Canada/Mexico, $35 rest of world.
