Roll, tool, canvas containing...info request

[Darrin Wright]

Question. Does anyone have a correct or original tool roll holder they could measure the length & width for me?
It has to be original and not a substitute that does the job.
I need to work out how big the toolbox on the gunners front floor of my Aust LP1 should be. I know it is 16” x 6”, have no idea on height. I am thinking approx 4" like the tool box in the Aust LP2/2A.
But the Aust LP1 copied so many parts of the Canadian/British carriers, I welcome any info for consideration.
It has to fit the tools in the packing list (attached pic).

Thanks in advance
