Whilst looking at the preserved railway stock list on uklocos.com, I noticed that there is a Wickham trailer (converted from a trolley) listed on that site that doesn't appear to be on this site, this being:
Type 17 673 of 1932, also carried DE900393

Also is a recent pic of the frame of 9043 - showing that it's still with us (probably best regarded as a trailer now?)

Apologies if the first one is indeed on this site and I've missed it. I didn't see either of these on a recent visit. Wittersham Road is difficult to get to by bus, could only visit Tenterden, Rolvenden and Northiam - the rest will have to wait for a future visit!
Thanks.
