Leopold Lazarus Ltd were steel stockholders with various sites around the country. I used to sell them little felt pads to be placed between sheet metal to prevent sticking, but I don't think I ever visited their place in Summer Lane. They are, I believe, still trading under the name Macsteel Ltd, but not in Birmingham,.
Lyn, your photos bring back memories of an ill-spent youth! I don't know what it was about it, but when I first realised that I liked beer (!) Summer Lane drew me like a magnet. Two or three of us would catch the No 5 or No 7 bus in Witton Road, get off at The Salutation (may its memory be forever blessed) and then work our way back up to Six Ways. I can't say I drank in every pub in Summer Lane or Alma Street, but I think I managed to get a swift half in most of them. I also played darts (for The Brown Lion, Hall Street) and we had many a match in various Summer Lane pubs. I can honestly say, hand on heart, that apart from the odd "falling out" between drinking partners, I never encountered any serious trouble in Summer Lane. Or maybe I was just lucky. The pub that sticks in my memory is The Cross Guns - an old regular there took a liking to me for whatever reason. I think that was one of the first Summer Lane pubs to be demolished, but I'm sure someone will correct me if I'm wrong. I also liked The Woolpack for both its atmosphere and its architecture. They were real pubs for real people - beer, cheese cobs and darts, as my old man used to say.
