A little update,
on the other thread, there was mention the nc-60a had been changed, and the Big Bertha cone is not in that assortment. I just confirmed that! I saw this listed on Belleville's website with the description "The nose cones in this packet are a Big Bertha style.", so I ordered it but the assortment is now 3 nose cones (on the right, below). I found the picture on the left (the original NC-60A) on Discount Rocketry's website, but I bet they are now the 3 set since Estes changed it. now I am sad...
I emailed Belleville to ask them to update their listing...I was hoping they had old stock
