I vaguely remember seeing a Lee Speed with a Davidson setup such as you would see on a Fraser single shot, and sometimes other makes.

That setup would look good on a LS. It looks good on anything. The only trouble is there is no allowance to take up wear, so the shooter has to be very careful to keep things clean. They look very simple, but after making several sets I can assure you they're quite time consuming to make.

Using a small diameter scope certinly improves the look. It doesn't overpower the lines of a slim rifle.
