There is now a page describing some of the how and whys of her existence and it is sad that there is no mention of her in any posts after September 2019 in any public streams in use by NEMT under their current management.
Posted on September 5, 2019 – “Not be long now, engine box and thwarts nearly done. Foredeck next, these guys are doing a fantastic job on the Cygnet”

The were no more posts for Cygnet in the Face Book stream from which this post was taken but there were posts made from 2020 onwards, in a new stream were she can be seen in the background, and looks to be completed and on a trailer. Access to that steam has recently been restricted for some reason and it appears that she is now in storage.
A picture of the finished Cygnet on a trailer has been found on X and it appears to be about 4 years old.
I heard this morning that Cygnet was sold at auction and had gone to a good home. 🙂
