UK offices in London, Glasgow, Edinburgh, Manchester, Liverpool, Birmingham, and ,Leeds,
Overseas Brussels, Paris, Berlin, Vienna, Amsterdam, Milan, Constantinople and Hong Kong

Thanks once again to Pablo from Barcelona 

Here are some really nice illustrations of leisure and social meetings, a theme very usual in automobile and Tyre adverts in 20s (golf, Club, Parties, beach...)

We are once again indebted to Pablo from Barcelona for his help in finding NBR memorabilia, the picture below is from E-Bay with the sellers description

Description from seller
Sign from Garage Wall - or somewhere like that !!  Measures approx 24" x 151/2" and is painted on Galvanised steel
Has holes drilled in the corners where it has been screwed to a wall and also scratches on the surface, but I would say it is it is a reasonable condition. Don't know the origin or history only that I bought it at an auto jumble sale about 10 - 15 years ago and it hung on a wall in the house until recently when we changed the look of a room so this and some other signs have to go as they no longer fit the decor 

Sounds like he got married !!!

We are indebted to Pablo from Barcelona who has sent us
another contribution to the graphic history of North British
 Rubber Company rubber company. 
A postcard from 1921 he saw on the web.

TYRE BLOCK EXPANSION
To triple output within a year

Perhaps it is the Tyre Division where the first benefits of our modernisation plans have 
been felt. Original equipment  contracts for new cars have increased at a great pace, while 
sales activities in the tyre replacement  and bus mileage markets are highly encouraging. 
Within 12 months the out put of US Royal Tyres will have trebled

Tyre Factory Manager

DEPARTMENTAL PLANS

EAST MILL BANBURYS.. 
To supplement existing mixing capacity comprising modern high-speed No 11 Banburys, 
plans are being made to install one additional 84” mill at each unit. This will enable reductions 
to be made in machine cycle times and thus effectively increase our present volume output.

DUAL TUBER EQUIPMENT  
Capacity in this department is being increased and present equipment improved to provide 
better cooling facilities, thus improving the quality of treads.

SOLUTIONING EQUIPMENT
To meet expanding production requirements it will be necessary to materially expand 
our existing solutioning capacity..This will be in operation by the autumn of 1958.

PREPARATORY
To enable the preparatory to keep pace with these increasing demands new banner cutter 
and bead coiling equipment will be installed this winter. The installation of these additional 
units will make necessary a re-arrangement of the Preparatory Department will then be located 
on the 1st floor

TYRE BUILDING
During the remainder of 1957, new Akron Servicers will be fitted to those passenger and truck
 building machines not yet equipped with them . Apart from satisfying our production needs, 
these modern servicers will considerably enhance the quality of our finished tyres.

CURING
By the end of the year the old and uneconomical autoclaves will be removed and 
sufficient modern shear –strip presses installed to meet requirements for heavy tyres. 
Still more B.O.M. presses for passenger tyres are on order and will replace obsolete 
De Mattia  mpresses by the end of this year, followed by further passenger B.O.M. 
and heavy service shear-strip presses during the winter to enable us to meet 
increasing sales requirements
