I searched the archives but only found one thread about Colt boxes and it was from 2008. It also dealt with the old cardboard boxes from the 40's and 50's. The information I'm seeking is about the newer boxes and plastic cases. What were the dates Colt used the fitted Styrofoam inside a cardboard sleeve box? When did the switch to the Formed plastic case inside a cardboard sleeve, and how long was it used? When did they switch to the egg crate foam lined box like they use now? Thanks!
