A brief update as I tackle the latrines!
I had to rebuild the one I’d tried earlier, it just didn’t quite work. Then, as is the way with personal builds - or at least with me - I started remembering even more.
Out side the karzi was a 6’ table replete with aluminium washing bowls, a jerrican of water and Army-issue soap - or at least there was for the officers’ one. Manufacturing a 6’ table in this scale nearly finished me off. Several attempts using stretched sprue for the legs just didn’t work, so in the end I decided on lengths of fuse wire, and plastic card. The bowls were from lengths of plastic rod. The whole just about discernible in the pics below:

And now I either need a lie-down, or a trip to the opticians - or possibly both!
