I picked up 6 hardbound reprints of the Model Engineer and Amateur Electrician magazines From 1901,02,03,04 years they were reprinted in the 1977. They have some great stuff in them, they also have some stuff that would have the nanny police, going nuts such as their coverage of home radium experiments

the question I have is in regards to some letters that follow the address of some companies.
Like this:
W. Macmillan & Co. Mar Street ALLOA,N.B.
or
Clyde Model Dockyard and Engine Depot, Argyll Arcade, Glasgow, N.B.
What does N.B. stand for? At first I thought it might be New Brunswick Canada, but googling it it comes up with UK IP addies. But no clear explanation of the N.B.
Thanks
