3.7" info request

[Fred]

Hi there
I am looking for a dimensioned drawing of a 3.7" aa shell. I'm hoping to make a dummy replica to fill a case but just cant find an accurate drawing. Any help would be appreciated.
Thanks
Fred

There's a decent plastic one for sale here if you wanted to save a lot of effort.
