Bomb peckers !!!
Hi Misk,, Yes you are right on spot with your recollections

the Box-Carton Company manufactured there as you rightly say,
The most notable building was Brandeur,s Pen & Knib a massive
3 Storey building probably 1870,s circa build or older,
This was about a hundred yards further down New John St West
almost to junction with Summer Lane (my old haunt 1960,s )
There were quite a few "Solitary facias" left intactum after "bomb"
damage,, my father said it was to stop people "peckin" the sites,
Scavenging,, Lead pipes, copper wire & Anything get their hands on,
Also the Builders redeveloping in later years left them as Boundary
Markers etc, why knock them down if nobody going to pay them

Ok, good of you to drop in & take an interest, Cheers Nottingham Misk
Best regards John Y
