The yellow dot is a mark put on the case my ACME SURPLUS of Toronto. The star appears to be hand drawn and NOT a stencil as NORMALLY would be if military applied.... Might I suggest that it was someone with too much time on their hands. I had a bright blade years ago try to sell me a 4T in the chest with a yellow blob that he claimed signified it was special forces, SOE, SAS etc...... By the way ACME marked the cases in Englandicon to prevent another unscrupulous dealer from laying claim to them..... Now you have the story of the yellow blob and MAYBE the red star. I think JohnR picked all the LB rifles out of that shipment and perhaps he will elaborate on my story. That was a long time ago....over 50 years ago and the mind is the second thing to go... :-)##
