TO: ALL CUSTOMER ENGI NEERS The attached News Letter is intended to replace all News Letters issued since the announcement of the Model C in January, 1959. All information considered pertinent at this time has been grouped by mechanism for your convenience. This should be particularly helpful to new Customer Engineers who have not received back issues of News Letters. ---ElB5M--- Every effort has been made to reduce the number of items in this pub- lication. Most Parts Manual corrections have been deleted since it is assumed that the changes were made upon receipt of the original News Letters involved. Technical items have been omitted if they no longer apply or have been included in other publications. Those items con- sidered helpful to a majority of the Customer Engineers have been retained. The 1961 issue of the ET Parts Manual will make possible a still fur- ther reduction in the quantity of News Letters required. c,t'~~ C. L.
