Form und Inhalt
In the letter Schlesinger provides information on two special lamps for the Zeiss projector as requested. The two lamps are made by Westinghouse: 115 volt, 1,000 watt 1MPS52/3 export mogul base and 6 volt, 10 watt bayonet base double contact. Schlesinger also references a 100 watt lamp but states that he doesn't know if either Westinghouse or G.E. has ever made them. He instead suggests using a standard projection or spot lamp instead.
