Sleeping Cars - West Wales

[87J]

Hello,
I assume this is the right place to ask this question rather than in the Rolling Stock area.
I am researching the Sleeping Cars used on the Carmarthen/Milford Haven route in the late 1950's/1960's.
On a website recently I saw a comment that the Hawksworth Diagram J18 6-wheel bogie Sleeping Cars (W9082W - W9085W) saw out their last days, in BRWR service, in the late 60's on the Milford Haven route.
From my own notes and observations and such photos as I can find, I only saw the BRMk1 Sleepers in use.
Does anyone know if these cars were used on this route? Does anyone know which type of ex-GWR cars were used and when they finished?
Thanks in advance for taking the time to reply,
Regards.

If a reply is not forthcoming another place to try is the BRCS group on Yahoo run by Robert Carroll.

Another place to ask would be the GWR E-list also on Yahoo.

Hello,
Thanks for your replies.
I am already a member of the GWR E-list and posted this question on the 5th December; no response as yet.
I was unaware of the BRCS Group and have now applied to join and I will post the question there as well.
Regards,

Well, some 12 years after my original post I found an answer ! I came across a website railcar.co.uk which had a section on DMU Tail Loads and behold there was a photo of a Cross Country DMU leaving Swansea High Street for Carmarthen with sleeper W9083W attached.
Presumably the sleeping car had been at Swansea for repair or maintenance and this was the most convenient way to get it back on it's normal working.
