* 2” Cut Master from serial #16209 to #17647, 123 Cut Masters were built before the war. Spiral Drive V. T. L.’s were manufactured only during World War II, with the exception of 91-74” Cut Masters shipped between 1943 and 1944.
You will note that there is an overlap between the ending of one model and the beginning of the next. This is explained by the fact that the old style was being supplemented by new style machines.
