Aeroplane Cannon Shells?

[blondebombshell]

Hi I'm new to the site but would like help to identify some military shells that I acquired recently. My boyfriend says that the shells in the picture may be a string of shells from 1950s aircraft cannon and that they are of 30mm calibre. Can anyone be of any more help to me and are they of interest to any ordnance collectors out there.

They look to be ballast rounds, used in place of live rounds to simulate the weight of a fully armed aircraft during training.

Cheers,
Andy

Definitely Aden 30mm Ballast rounds

As above, ballast not practice rounds.

To answer the original poster's question, they are for the 30mm Aden cannon but I suspect later than the 1950s. The Aden was a revolver cannon developed from the German MK213C and used in most British fighters throughout the second half of the twentieth cantury.

I'll guess they are dated 1957!
The date is cast into the round in a slight recess

I also agree, Definitely 30mm Aden Ballast rounds.

I had 4 of these not long ago. 30mm Ballast rounds Aden (as stated quite a lot above) Mine were dated sometime in the 60s I think.
