Yes, that's Dunlop, but as I've mentioned before it was never a Fort, just Dunlop Tyres. I worked at Pressed Steel Fishers next door (formerly Nuffields) and we just called it Dunlop.
The misnomer "Fort Dunlop" arose from good old Black Country slang in times long before I was born, but I learned how it came about from old timers working there.
Many Dunlop workers arrived each at Dunlop by barges along the adjacent canal.
Along the way, when arriving at pick up points, the barge master or others, would call out "All for't Dunlop" (All for the Dunlop), from which the myth of Fort Dunlop was born.
