Disposal at auction categorisation

[Great War truck]

At the GDSF last year there was an FWD which had a large letter A painted on the side of the seat. This seems to be very old and I was wondering if it related to a category that the lorry was placed into for disposal. Looking through some photos I came across two other vehicles which had been marked with a B and a C. Can anybody shed some light on to what these markings might relate to?

Thanks

Numbers from the salavaging companies / dumps like Slough?

l would like to put forward one idea l have come across with sales disposal catalogues from the auctioneers own copies they all use their own  method of grading the items which gives a idea  of condition for them when selling

Could possibly be identification letters for the port they were leaving France through. "A" was Calais, "B" was Boulogne & "C" was Havre. Letters possible applied by the VRP as instruction for the RTO as to destination of the vehicle.

Thanks guys. Some interesting ideas there. The Thornys marked B and C were returned to Slough and then ended up in Basingstoke at the Thornycroft factory. Both were in very poor condition having suffered collision damage. I have not yet found any other markings but need to do some more work. I need to find more photos of them with these letters to make the connection. Thanks for your input.

Tim, could the top no. be the chassis no. ? The lower group could well be a date, 4 / 2/ 20  (I have seen dates written like this on War time docs.)

Any more pics of the dispersal sales please ?

I'd read it like that Tommo, and shipped home through Havre probably to Avonmouth but quite possibly through Chepstow or Newport and then on to Slough.
