Jim,
Very nice rifle and you are likely to find it easier to carry than smaller folks. BTW, your boy may already be looking forward to the day that he can hunt with it.

Before you put in a blank, please consider the benefits of the Marbles folding barrel sight, as backup for the receiver sight.
This made much sense for my 1886 Bull barreled 45-90, but may not be for everyone. Here are a couple of pix:
