We're thinking along similar lines there. I managed to source an original full sight for one and base for the other. I've fitted one already the other to go on soon but I have NOT wound the elevation wheel in order to put no stress on them.
It's interesting to note that later sights have a metal centrepiece which does the flexing.
The more I think I know, the more I realise the less I know.
