Wanted: 2lb A-tk round

[cpetronis]

Hello,

Our unit will be participating in the annual Mil-veh open house in Noaksville, VA coming up in September. Our task will specifically be to portray the crew of their Valentine MkIII. It would be really nice to have a correct 2lb gun round to show the public what goes downrange toward the bad guy.
I've never needed to look for a 2lb round before and so don't know how rare they are or what the going rate is. Does anybody have a repro or original they'd like to sell?

Thanks,

Chris
