Mrsperfect,
You can reminisce about your early childhood in Balsall Heath, I'll just add that no I never had occasion to enter 43 Hereford Street. It's also worth mentioning like a lot of Balsall Heath it has changed drastically over the last 40 years or so. There are none of the original houses left in Hertford Street and they have even converted the Crown to housing which I think that there is a great possibility it's what it was originally when first built.
