17pdr Brass Case specifications 77mm HV

[TankGunner25]

I was wondering what the specifications of the brass case of the 17pdr shell was. I know it is 76.2x543R but i want the information especially in terms of its dimensions like how rifle brass cases are done.

Neck Length
Shoulder Angle, Length, Diameter
Body Diameter @ base of shoulder
Body Length
Body Diamter @ Rim
Rim Diameter
Etc.

Doing some CAD drawings and want to make them as accurate as possible

Also the same information for the 77mm HV brass case. I know it is 76.2mm x423R. Just the other information

Thanks
