DickJones,

Welcome to the forum.

Until you are able to get to a gunsmith, a small amount of thick grease will
often be enough to hold up the leaf sights. It has worked for me on some
guns in the past.

Was the bead suposed to be nestled into the notch ? - I have always worked
on this principle but that is not to say some guns were wighted in with the
bead at the same height as the top of the leaves.

I find if you always have the bead nestled into the notch, you get a consistent
sight picture, where as you can have slight variations with the bead at the same
height as the top of the leaves

Hope this helps.
