Will you please have one new dynamo produced for us complete to LO's. D.75267, 75270, 72244 and D.75275 with the exception of D.75274 magnet case, which we require making to the same external diameter but .350" thick instead of .312". To accomodate this extra thickness the field winding should be wound with 19 SWG. Enamelled & paper covered wire instead of D.S.S. wire. We will arrange to supply the wire for this purpose.
