Not my room I'm afraid. When I ran stacked '57s they were just bolted bottom to bottom, and stood on three legs. In affect, they were sitting, two stock legs, attached to the "top" of the (inverted) lower panel, and the whole panel leaned back against a third leg that went from the center top of the array, down to the floor, about a foot behind. I didn't have the Decca ribbon tweeter in the middle either, I've heard that was an awesome combination. I'm not sure if I have any pictures of it, but I'll look. Double '57s were a really good ESL system for sure, but I think there are a few more modern ESLs that beat it over all... Several Acoustats, especially Spectras, most Soundlabs, and of course Quad ESL-63s. As I've mentioned before, I've never regretted trading in my '57s when the '63s came out. I think '63s were the best audio purchase I've ever made.
...still, I'd love to have that pair with the nice stands & Deccas!
