I like the water bottle packaging - a few years ago I had to pack a huge CD copying machine for sending by courier, I ended up using five or six water bottles at the ends as a substitute for the giant bubble packing material, plus big bags of crumpled newspaper. Got to the buyer safely, which is what counts.
Today was another interesting one - another car boot sale, where I got 870mm of lens for £45!
Two Bell and Howell large-format projector lenses, I think for a 6x6 slide projector - the big one is 300mm and came with the wooden box and a condenser, the smaller one is 200mm. They both have these long metal tubes and screw in and out for several inches, so would be very suitable for the people who like to use projector lenses for photography. The need a good clean, but for £15 for the two I'm not complaining!
A Sigma 100-300 AF 4.5-6.7 for Nikon - very clean and working well - for £20
and a Sony 18-70 which is partially working - manual focus only but focus confirm and metering are fine. Not sure what that's about, but it cost a tenner and I can't really return it so I'll sell it for spares/repairs and keep my fingers crossed. It's the risk you take with this sort of sale.
The 330ml can is there to show scale, I think it's a more convenient measuring unit than cookies for these big lenses.
Also a working 100mb Zip drive for £3, they're usually good for £15-£20 on eBay, there must be a LOT of people with legacy systems out there.
