Since I've been working on some lineage axes I've noticed a few things I wanted to post. The kenner han solo blaster heat sink greeblie on the axe could either be A new hope version or Empire version. Ive bought a few of these and I've noticed the heat sink on each blaster are slightly different from each other. The screen accurate one has a real screw on the right side of the blaster and a fake one on the left side. Also the screw hole on the screen used one slightly cuts into the raised frame of the vents on the heat sink. I found one esb vintage blaster that was correct and one 1996 version that was. Also on the screen accurate one there's a groove that runs a cross the front of the heat sink. Not all of them have it. Here are some comparisons. The one with the red circle is screen accurate.
