Info needed: Trailer socket Humber one ton

[Robert Sexton]

Hello Chris,about the serial number, you are probably right ,the "eight" is a bit distorted and looked like a "B" to me. I will get a strong light and a magnifying glass to verify it.I have attached a pic (poor quality) as the trailer was when it came to me.The brackets for the tail lights were as you describe,one on either side with the bracket taking the Lucas with the red lens.Mine had late after market combination Narva lights ,definitely not original.The number plate was mounted central below the tailgate but I do not think that is original either as it was fixed direct to the chassis and not to a bracket. There are mounting holes for something central to the chassis at that point, I think it unlikely that it would be for a number plate bracket as that is covered when the tailgate is down and locked,it would be more likely to be on an outrigger on one side. Mine had the original reflectors (common to the Humber) mounted central on the lower part of the mudguard.In the centre of the tailgate is a metal triangle with nine cats eyes inserted in the three sides, the centre was painted red.
My Humber has 1954 stamped into the air cleaner and it would be likely that the trailer is about the same vintage.I have yet to find out out exactly how the trailer socket was connected to the Humber.
I couldn't even think of being able to work in the dimensions that you guys do. Regards, Robert
