Roughnecks Leather

We have been commissioned to make a custom Western holster rig as a gift for the Uberti 357 Cattleman 1873 with a 4 3/4" Barrel. To ensure the best possible fitting holster it helps for us to know the length from tip of barrel to rear site and tip of barrel to front of trigger guard as well as the width of the cylinder. We have made many holsters but this is our first for an Uberti. Does anyone out there have these measurements so we can be certain this is a perfect Christmas gift when we are finished with it? Thanks in advance.
