I had some "Maindy Flyers" tights in a club auction a couple of years ago made by TAL that were lycra and no padding and did the job until the lycra disintegrated making me look like a Norah Batty tribute act as well.
I think TAL were absorbed into Endura and, like you, I couldn't find an exact replacement.
Perhaps dropping a query to the Flyers to see if they still order similar garments and from whom would prove useful.
