In reading many older post about stones you can definately see the trend from that time for a particular stone like you mention. One must wonder what the next trend will be?

That B. T. & Co. is the trademark of Bösenberg, Trinks & Co. They were in business as resellers/makers/suppliers of hones, abrasives, wind-up stroppers (based at Deutsche Schleifmittel Werke, Hamburg) and sharpeners for safety blades, etc, at least up until 1923/4, when it became Schleifmittel AG vormals Pike & Escher and relocated to Sonneburg, Thuringen.

Thanks for the information Neil,
just a view adds that might be of interest.
Bösenberg, Trinks and Co was a direct follow-up or subsidiary company of J.G. Escher Sohn. The first owner of B.T.Co married a granddaughter of the escher family. B.T.Co also owned or rented some of the Thuringian quarries the J.G. Escher had before.
The Schleifmittel AG exists until 1963 when it was taken over by the VEB Vereinigte Porzellanwerke. However, the Schleifmittel AG kept the logo that B.T.Co had used (man with knife and sharpening stone) still for their products, even for a certain time, as you can see in the following head of a letter/bill from 1937.
