The type classification is one by formulated collectors and not by the U. Edwards and the classification was extended and codified by James Mc Duff. The illustrations are examples and I am not showing all of the varieties that exist of each type. Categorizing early disks into a Type I and a Type II was originally the idea of Charles A.The problem with counting attaching parts is that some are permanently fixed to the back of the insignia. On October 8, 1907 the War Department issued Circular No.So, are the parts that are not removable counted or not? 68 that described new insignia to be worn on the standing collars of enlisted men's service uniforms.Clay, or kaolin, pipe stems look a bit like narrow white tree branches with holes down their centers. Clay pipes had very long stems and as the stems became clogged, the ends would be broken off and discarded. Harrington, an archaeologist with the National Park Service, studied hundreds of dated pipes and realized that the stem's bore diameters directly related to certain time periods.
For those who find that odd, I am only following established terminology that insignia collectors use. Forest Service, the Civilian Conservation Corps and others.
Lastly, a slide on the side of the stem was added for removal of the stub and for raising the candle as it burned.
Although, I do not find this classification system totally satisfactory, it is understood by collectors and therefore I will use it.
Early types were solid cast brass construction usually in two pieces the stem and base. Construction techniques changed through the years allowing for economical methods to make brass candlesticks.
Cores were used to cast hollow voids in the base and stems saving on material used.
