Lidu do a Red Lantern shell with a strobing tail in 6", it's available in the UK - don't know about the brocade burst though, difficult to arrange in the same shell. Maybe it was 2 shells that happened to burst simultaneously??
It's possible that it was 2 shells, possibly a 'stacked' shell or 'double bubble', but the parachute really looked like a pistil. After talking with some of our manufacturing people, they said it would be very hard to not destroy the parachute with the hard break of a brocade...I wonder if they found a way to do it?
