Natrium C-Hing, thanks for your information on the K98K forum.
Actually, during late WWII, the German armed force already faced shortage of supplies for repair and maintenance. So in the real battle, no matter what they got, if it fit to fight, they will use it.
That's why Natrium C-Hing you are right, no matter H or Solid band, both bands were seen in a lot of war photos since 1943 till end of the war.
I will take your advise to keep all parts together.... as it is somehow, hard for me to gather these in Hong Kong.
By the way, can you give me some information on the lenght of the barrel? Many thanks
