More on the company and the pump.
Aerite is a neat, functional little pump, manufactured under this brand name by Walters and Dobson (see below) - with the good build quality and (generally) screw fittings to enable them to be dismantled. All the ones I've seen operate on the single-stage principle - one piston in one cylinder pushing out air at the end! Because of their relatively small size, you often need to keep up the pumping frequency with your foot to get a good volume of air going they don't usually have inbuilt non-return valves.
When originally supplied they would have had NR valves in the hose connector at the pump end. But I've seen a number without this - maybe hose replaced later in life? Sometimes those without NR valves in the hose connector do get air into the tyre successfully - but high-frequency pumping is needed!
Aerites don't usually have pressure test valves or pressure indicators - not the ones I've seen anyway
Sutty whose pumps are mostly smaller, similar to Aerite. These come in a range of pretty colours some come with a dial-type pressure gauge on the pump.
Walters and Dobson company
Walters and Dobson Ltd. (WAD) were a Sheffield manufacturer who made a range of high-quality pumps. The range included an advanced and beautifully designed double acting pump and a series of single-acting examples of various sizes. The firm was jointly founded in 1922 by William Mansfield Dobson (b.16 Feb 1896, d.15 Feb 1965) and Booth Walters (b.12 Aug 1895, d.23 Mar 1983).
WAD was in business in the same time period as the more famous Sheffield pump maker, Wm. Turner and Bro. (Kismet). Apparently, Wm. Turner and Walters & Dobson were very close for as long as the original owners were in place. In fact, during WWII the two companies worked together in support of the war effort and some details of their pump designs "crossed over".
Following World War II the WAD business was never the same due to ill health and responsibilities relating to the defence of the realm during the war. For instance, W.M.Dobson’s health suffered badly due partly to him being CO of the local Home Guard and Anti Aircraft Command Battery during the war. The firm passed onto the next generation after the founders and eventually, the Motor Accessories activity (including pumps) was sold. The intellectual property rights e.g. registered designs, patents etc. of this business were acquired by PCL (Pneumatic Components Ltd) also of Sheffield.
As a matter of interest, I have recently supplied a restored WAD pump to the son of William Mansfield Dobson, one of the founders. He wanted it for his family history project, never having seen one in his life and wanting to tell his son about the pumps! I am indebted to this elderly gentleman for providing me with the above information on the history of the firm and its founders.
WAD also manufactured lightweight, less heavy-duty pumps under the ‘Aerite’ brand in Chesterfield
