Not long after, I stumbled across two additional Trlbys, so I could stack them together to fly as a Trlby triple-stack:
Good things come to those who wait ... keeping a regular eye on eBay resulted in six more Trlbys, and the triple-stack could be extended to a 9-stack:
So, clearly, Flying Fish had to fly the two 9-stacks together!
Apologies for the less-than-perfect picture of the two 9-stacks flying together, but flying one of the stacks, trying to avoid it catching its own tails on its stacking lines, trying to avoid the tails of the two stacks getting tangled and taking a picture at the same time was a bit of a challenge. This was the only picture with the two stacks more or less in focus ...
One thing was clear: if we are ever to fly these two 9-stacks at a festival, we will need a dedicated ground crew to help us set up and take down.
