One of these two kits featured in an article in Model Rail but it looks like my copy of the magazine has not survived one of my clear outs. I also seem to remember some discussion on real-life examples possibly on RMweb.
Checking on the Model Rail Index featured on The UK Model Shop Directory, the Noch version featured in issues 177/178/185 from 2013. I could have sworn I saw it in a mag from the last couple of years, in a feature on fiddle yards(?). It says that a layout featuring it is in issue 185.
If you search in RMweb for segment turntable there are mentions of it being launched in 2016. I'm confused.
