I know Jon has a couple of these in his personal collection but since he hasn't posted yet I thought I'd chime in.
Gardner-Lucas were makers of good old Candy Cigarettes back around 1910. Its neat to see how close the Candy Boxes replicated their Tobacco counterparts. Its a shame, as you pointed out, that they didn't put in T-206 like cards in along with the candy... could have been one of the first "parallel" sets in the hobby 
I believe that your supposition is correct that you have the shell of the candy box but a slider that came from a Tobacco pack as the Sweet Caporal examples in my collection didn't go so far as to have a fake tax stamp on them.
Here is an example. If you have another Piedmont candy box or anyone else on the board has one and would like to trade for a Sweet Caporal candy box... feel free to email me!
