BTH Bijou

Variometer Crystal Set, Circa 1923. B.B.C / G.P.O Stamp No 861

This is a Type C Form B.

B.T.H = British Thompson-Houston Co Ltd

Working.

Purchased from a dealer. Requiring only an aerial and an earth and no power, this set will work forever.

The mahogany cabinet is original. The detector did need work, a new piece of Galena and a "Cats Whisker" kindly supplied by Gerry Wells.

I have now obtained a pair of BTH headphones to go with it. The set remains working permanently.
