Historic logos can be useful and reliable information sources when researching and documenting the modern history of diving equipment. Here's a case in point.
As a retirement project, I am studying French basic diving equipment manufacturers operating between the 1950s and the 1970s. By way of example, Kent Rubber Company of Anglet in southwestern France was such a manufacturer, making hot water bottles, swim caps, fins, goggles and masks as well as distributing spearguns. Illustrated below is the firm's "Submarine" brand logo:
I was intrigued by the English name of this company located in France's Basque Country, but I was astonished even more by the firm's brand name "Submarine" written in a cursive style I had observed elsewhere:
The 1950s advertisement above is for a Trident swimming cap from the Submarine product range of W. W. Haffenden Ltd., operating at Richborough Rubber Works, Sandwich, Kent. From my childhood I remember this British company's Submarine Clipper fins, which were sold in many sporting goods stores here in the UK, e.g.
There is a pair top right.
So what's the evidence of a link between the Kent Rubber Company of Anglet near the Atlantic seaside resort of Biarritz in France and W. W. Haffenden Ltd. of Sandwich in the English county of Kent? Let's consider the facts.
- Both companies' product ranges came with the brand name "Submarine" written in a lookalike cursive font on their respective logos.
- Both companies had some connection with the name "Kent", the firm's moniker in the case of the French enterprise and the firm's address in the case of the English manufacturer.
- Both companies manufactured the same range of rubber domestic and recreational goods, namely hot water bottles, swim caps, goggles, fins, masks.
W. W. Haffenden Ltd. was a family-run concern until 1960, when it was acquired by London Rubber Company. W. W. Haffenden Ltd. became "Haffenden-Richborough Ltd.", while the old brand name "Submarine" was replaced with a new brand name, "Britmarine", written in a now familiar cursive font:
These leads caused me to surmise that there must be some link between the English and the French company. And so I was delighted yesterday when I finally located some supporting evidence from the 20 July 1967 edition of

and from the 10 August 1967 edition of

So there we have it. As artefacts from the past, historic logos can plant a hunch in somebody's mind and inform a follow-up search for further evidence in the online and printed literature to verify what will otherwise just remain a hypothesis.
