Four dials by the Hager family

Evans bought these dials variously in Berlin, Monte Carlo and 'in a wine merchants shop at Carlsbad.' One source is not recorded. One is signed by Michael Tobias Hager of Arnstadt, another by Johann Michael Hager of Brunswick. On the basis of similarities in the mechanisms for raising the gnomons, Evans was able to attribute the two unsigned dials to the same family of watch and instrument makers.
