The front sight (marked with +.060) on my 1949 Long Branch No.4 Mk1* is so loose I can push it with my finger. There looks to be something like a wedge in the sight base at the front. What is it for? Is there some way to use this to tighten the front sight, or some other way to tighten it? TIA

There is a little clamp screw in the front of the sight base. You will need to make a tool to tighten the front sight in place. I took a small Phillips head screwdriver, cut the end off and cut a slot to fit the head of the screw. Hardened steel, so I did the cutting with a disc in a Dremel.

On some of the Lee Enfield Number 4 rifles, there is a "screw" that you can tighten up a loose front sight with.
You will have to make a tool for this, sort of a "reverse screwdriver" that has a slot instead of a blade.
Take an old screw driver that has the proper diameter to fit the "screw". Then cut off the blade so that you have just the shank. Put the shank in a vise, upright, and make a hacksaw cut about 3/16 inch deep in it. You might even be able to make two cuts, or, put two hackblades together on your saw..
Take a narrow file, and widen out the cut you made so that it just fits over the protruding "bar" on the front sight "screw" head. You can now turn the "screw" and tighten up the loose front sight blade.
Some Wartime fast production models did away with the "screw" and used a front sight blade that had a tiny slot milled into the dovetail of the front sight base. The base was slightly oversize for the dovetail, and when the front sight was forced into the dovetail, the sides of the base put some tension on the sight to firmly keep it in place.
