WW2 Military plan sheets

I think I have something that would interest members that are into WW2 stuff.
I have a small cardboard container with about 34 sheets approx 2.5 ft by 1.5 ft dated 1942 which says.. By Authority Modern Printing Co. Pty Ltd Melbourne. They seem to be detailed scale drawing of most of the weapons used back then including Vickers Machine guns, 303s, revolvers and many more plus even a scale drawing of a military bicycle. They look to me like they have been copied from blueprints.
I think anyone wanting to make replicas would love these. For some reason I am having trouble uploading pics from my phone to laptop as only 1 pic would upload which is one for the Vickers. I will try for more pics and if successful I will post more.
