Well done Perkel. You have more patience than I do !
I can vouch for the quality of the hi-matic which I know took a xmas card photo which was used by an international agency one year. Sadly most of this stuff came to me as the result of two family bereavements so Im only too happy to see any of it happily re-homed where it will be appreciated.
Unlike most of this kit, the vivitar 24mm was actually one of my own and is a very nice lens and is m42.
If any happy recipients care to donate to www.prostate-cancer.org.uk that would be good
