Two nice items I got on line earlier this week arrived today
A Zorki 4 with Leica-fit Jupiter 50/2 for £33 including postage - nothing remarkable about it, the lens is one of the silver ones and in really nice condition, the camera has a shutter problem at low speeds but is otherwise pretty good. £33 is a bit on the high side but it's a charity seller and I think I'll still make a profit.
A Pentacon 135/2.8, for £12.99 including postage. It's the original "Bokeh Monster" that could be used on M42 or Exakta with the appropriate rear mount (I've also seen one with a custom-made mount for Nikon), and has a preset-ring 15-blade iris. It's the all-black version here:

It's boxed and looks virtually unused, though the box is very battered. The best part is that it came with an M42 converter and cap for Fujica S-mount, which is in full working order - it even does auto stopdown on a Fujica body, if the lens has a rear pin, which is pretty rare for M42 adapters. Those are being sold at £15 and up without the cap on eBay, so I ought to come out well ahead. Gloating a bit about this one...
