If it's who i'm thinking of, it was Woodcock freight. I used to take stainless steel in there in the 90s from Shepcote lane. The foreman was a bloke called Sid.
I noticed you're down as Tufnell driver, i did YTS there in the 80s, remember a couple of lads Stevie Rooker off the Manor & Jim off the Wybourn, i think Jim was seeing a gaffers daughter. Hope that helps.
I've just thought on, there was also a team in the yard who rented a bit of warehouse, i think ( 90% ) they were called Land Sea & Air, age is a right ******* to your memory.
