Andrea,
A far as I can make it out we are talking about numbers 68 to 80 Moland Street, I've looked in the directory's and from the late 1800's until they cut through the lower end of corporation street there wasn't much change. There was a Brass Foundry, an Iron Foundry with some houses and shops fronting some back courts similar to the ones you have photos of.
I can come up to the 1970's if you want me to, just let me know in the morning.
