303 British Canadian made DI Mk 7z

I have a wooden case of 1944 303 Brit that has been in the basement since 1954.  It is Canadian-made and I assume with a boxer primer.  Mk 7Z means that it is loaded with stick powder similar to 3031 (not with cordite).  There is a sealed metal spam-can inside the wooden case.  Can is sealed 

26 boxes of 48 rounds each.

I know the ammo is easily worth $1.50 a round.   The Canadian ammo is known for its quality and accuracy.   This used to be part of our stash of target ammo, before we changed over to 7.62.   

Someone may appreciate the collector value of the sealed can and the wooden crate.

$2,000 to a good home.
