Bite-me Tip-up Box Dimensions

[Ches.]

I have done a few searches and have not found any place that gives the dimensions of a Bit me Tip-up box. I like to make stuff and figure they have the size right. I think the box is 12" x 12", If that is right, what is the top lid and bottom front board/piece depth.  Looks to be like 5".  All of the rest I can figure out myself.  Any help will be appreciated.

Kind of figured these were just a fad, responses kinda reinforced it.
Thanks all
