Box dimensions for Smith Model 66-1

[gpfwvu]

I might get a Smith 66-1 with a 2.5" barrel. It has the box but not sure if it is the correct size. What are the width measurements of a two piece box for this gun (in inches)?

thank you for the help!

If nobody else answers, I can go measure mine later. I'm not home right now.
