Haven't a clue and don't really care. 'Lived' there some considerable time ago - Park Hotel (hotel being a misnomer if ever I heard one), Wellesley Street, Shelton, drank Marstons piss in the Norfolk Pub round the corner, and worked at Thos Willetts Foundry in Hanley. People and place both excruciatingly vile.
Useless info I know, but I had to get it off my chest (what's left of it post foundry work that is)
It has stupid or as we say "rinde eyer stewpid" .Port Vale. Oh and don,t bother with the post office in Stoke or Boslem (Burslem) as they are always on strike. Thats why theyare moving the sorting office to Wolverhampton. " At they lewkin at mey"
I live in Stoke, The previous descriptions are for the Leek Road sorting office. if that is where the International Claims departmartment is then as for address, "Leek Road Sorting Office" "Stoke on Trent" should suffice, the mail for Stoke is going there anyway.
Building is Brick Coloured with Red Signage, opposite is a poor quality B&B on the corner to the left, then a Kebab Shop, a row of terraces, then used to be The Roebuck pub painted yellow, now demolished for a 6th Form College building (in process of being built) to the right.
On the right of the sorting office is the main station carpark, accessed from Station Road.
Immediately before the carpark is the main vehicle access road for the sorting office.
Unsure why you would need that information, but I hope it helps.
