Tandems
1934 Cataloge
Tanderms were more popular before the war than anytime after as can be seen in the range offered. Tandems are not listed as such until Malbro too over and then only the Gemini Tandem in 1987. I would expect any Tandems made to be development of the pre war models.
As per cycles look as whole range for feachers to ID Tandem.
