Steel 30mm Aden but 35mm longer

[mark moose]

I've had this for years but only just removed it from my parents cellar. The case has no markings it's 35mm longer than a standard Aden, the belt on the case is 2mm against 3mm on the aden in pic. Has anyone got an id on this?

27mm Mauser case

27 mm Mauser aircraft cannon case that has been removed from the production line before being "necked down" to the 27mm calibre.
Made of steel and probably has no headstamp.

Thanks Chris. 27mm Mauser is perfect, a dig in the collection and I've got one!

Any headstamp present?

Mark does your partially pressed case have a headstamp ?
