Need schematics for WWII German wood M24 grenade case internal rack

[mdarnell19]

Hey guys,
Just purchased a original wooden WWII German grenade case. It does not have the internal rack. So I was hoping someone here with an original would be willing to give me the dimensions so I can make one for my case. Or even better, do a trace for me. I would greatly appreciate any help with this. Thanks in advance. Here are some pictures.
