Hi Gillian

It depends on what years you are thinking around
because that section, New John Street West corner of Pen Knib mnfctr
Brandaeur,s to Henrietta Street (Ambulance Station) & Whites Ironmonger shop,, well most of that demolished in the 60,s
There is a Garage now at the Junction N J St W & Summer Lane then
small industrial Units to the Pub corner Brearley Street & then more
Industrial & office Units up to Henrietta St & the old M E B place.
Some others on here have photos & probably a lot more info on the
questions that you are raising,, hang loose, retain Zeez leetle grey cells
your memory will soon be reactivated ,,
