German WWII HJ Diamond Insignia-This is the elusive accurate piece used on both the side cap and the Hitler Youth visor cap. These can also be used as the insert for the handle on the Hitler Youth knife; however, the size does vary so be sure of your measurements. The enamel is very good on this example. This diamond measures 25mm high and 14mm wide. Check your sizes if you choose to use it on the HJ knife. The two prongs are intact. This is also nicely marked on the reverse with M1/101 for Wilhelm Deumer.
