I agree, Larry. Modelling what we remember (or what we think we remember after looking at old photos!) is why many of us model a period that we lived through. I certainly plan to weather just about everything on Moor Street, possible by letting off a “bomb” of fine soot over the layout!
Later, in the smokeless zone era, Birmingham started steam cleaning its buildings, changing the childhood memories for ever. I returned after a long gap (30 years) the year that Birmingham hosted the G7/8 and was astounded - no old prams in the canals, etc.
