Reference #1...is an HGC Style mold, as is #2. These have the more rounded dome like the HGCO CD 145s. These have a larger style Star. No 1 is a light blue with some fizziness. No 1 has a small chip at the left side (about 90 degrees from the Star) . Note the threading or lack thereof at the top of the pinhole in NO 1. No 2 is slightly lighter. Couple pings on side of the dome. No 5 is a super Hmeingray Blue...a deep rich blue for the display. Has a small internal stress right at the base...looks llike a sir bubble right on the bottom of the base. Have to pick it up to see. I am calling it a small stress. It is small. All three for $15 plus shipping.
