Shown mark is one used by the company of [b]C.A. Lehmann & Sohn[/b] from the city of Kahla in Thuringia. The writing reads “LEUCHTENBURG” (above) and “MADE IN GERMANY” (below).

The mark form in itself was used (with minor alterations) between 1909 and 1935, the MADE IN GERMANY addition was however only used on items intended for the UK market and made after 1920, leaving us with a date range of between 1920 and 1935 in this case.
