Hi, I purchased this star some time ago with the intention of identifying it but, to date,I have failed dismaly. I have no idea of the nationality nor the period nor what it may be. It is of good quality and pretty substantial. The initials are "ARCA" reading top tp bottom and left to right. The central device are a pair of rifles crossed over a grenade. The star is in silver metal and the cross is gold metal. The rays of the star appear to have been individualy sawn. More than this I do not know. Your assistance in Identifying this item would be greatly appriciated.
With thanks, regards and best wishes Michael R
