One half of 158833.

As I think the other part is 57833 (See next Picture), this would be 52833 !! Anyway, both parts 0f TFW's 158833 are seen heading south on the M5 at J11 after being collected from Barmouth yesterday, and presumably en route to Cardiff Canton. Thanks to my son, Martin for the headsup. 2nd June 2021.
