Thank you Voyager for your kind comments.
If you can't find half hinges, make from exsisting by tapping out pin, (maybe have to file off end peening)
Cut away section of hinge on one half only, (just enough to allow pin to slide in)
See sketch below.
Reassemble hinge. (remember you'll need 2)
Remember to use modified part of hinge to lid part and face mod. outward.
That way you will easily be able to open lid and remove from bottom, to act as stand.
Took longer to write about than it took to do!
