Cullmann 40470 Quick Release Plate

Over the years I've accumulated many camera bodies and some lenses with a tripod mounting bracket. Each of these needs the 'male' Cullman Quick Release Plate (40470) to mate with various of my tripods and a focusing rack, each of which has the corresponding 'female' Cullman receptacle.
The early versions of the 40470 had a fixed second pin (to mate with certain video cameras I believe) and this had to be removed (unscrewed) but this is now spring loaded so can stay in place.
A further improvement is that the 1/4" Whitworth screw (for camera or lens attachment) used to require a 1p coin to tighten/loosen but now has a fold-away turn-key. This is important because, despite the small plate size, it can impede opening of battery and/or memory card access on certain cameras.

Your product description informed me of the measurements so it fitted my needs perfectly.
