Giles and Shuey's book generally does not treat handgun, rimfire, or shotgun ammunition, only ammunition that was used, or could be used, in rifles, such as .44-40, .32-20, etc. However, as the same types of boxes were used for handgun ammunition, the key identification features are the same and can be used to date the period of use of the boxes.
Don't get too excited over value. Unless full, with the box in mint condition, you won't send the kids to college on sales proceeds. There is more of it around than you might imagine, and I find similar stuff cheap frequently at garage and estate sales. The principal market includes those who have an old gun and want a period box of ammunition to go with it for display purposes. Older and unusual boxed ammunition can bring some serious bucks.
