Here are the promised pictures I referenced earlier. Hopefully this makes it clear:
ReducedDR.jpg - This is my Desert Rats box. The overlay is a template I created in Excel and as I need a new one, I just copy it and move it down as I have set up all the cells to be the same size.
ReducedAK.jpg - This is my Afrika Korps box opened with the overlay above so that I can see at a glance what is in each "cubbyhole".
ReducedMix.jpg - This holds AFDX, White Eagles and South Africa's War pieces. Those pieces that are not obvious are marked with the appropriate game: (Soviets: AFDX, Germans: WE).
ReducedTrays.jpg - Here are several of my counter boxes stacked up. You can see the design change between the older bottom ones and the newer style top 2. I stack them this way and they fit nicely on a shelf. You can see that the stack of 6 comes up to about the top of an opened laptop screen. not much space at all. I will probably get a PTouch labeler and label the visible side so that I don't have to pull it out to read the contents.
CaseReduced.jpg - I have two of these file boxes that I use to store the game maps, scenarios and campaign books. This is my 0 - H box as you can see.
My admin counters , as mentioned are in a similar style tackle box along with dice and a pair of stanley heavy duty tweezers - a must for handling stacks!.
