Very nice Hasag. I didn't know they were once made in Switzerland too. I guess we wouldn't have any doubts about quality. I've heard of a certain famed expression about 'Swiss Precision'.
Both men worked together in the Schatz company until E. Schatz died. Then M. Aschwanden used his own name to brand the lantern further on. The lanterns where never made in Swiss but put together from parts they had obtained. Later on M. Aschwanden didn't succeed in getting spare parts made for reasonable amounts/prices.

I know the site of Tom. My information comes from M. Aschwanden himself as I was fortunate to meet him.
