Tip Tops The Tip Top factory was on Tunnel Road, Hill Top, West Bromwich. If you travel on the Wolverhampton to Birmingham Tram you actually pass under the factory, there was a chimney next to the factory built so that the smoke and steam on the GWR line could escape rather than fill the tunnel - where the road gets it's name from obviously. I used to walk past the factory every day to and from my primary school. We also had a factory visit once about 1968 or 69.
