Please do not stand a gun up by putting a leaver in the bow of the trigger guard. This method of standing a gun up seems to be common on your side of the pond but the outcome of doing it is to push the guard off the centre line one way and move the trigger off centre in the other direction not to mention a dent in the wood.
One day it may be a heavy gun thin metal trigger guard producing an expensive repair rather than a picture to remember, and please do not do this with a lightly built Brit gun because the outcome could be extremely expensive to put right when the guard snaps off with the strain.

The only lessons in my life I truly did learn from where the ones I paid for!
