    [QUOTE=Wayco;1696061]So I'm digging through my AT 38mm reloads box and find this:


    I think I got this from Juan a while ago, anybody want to guess how old it is? It even includes a piece of thermite and long version of the old copperhead igniter:

    ISP/Aerotech sometimes used Hexadecimal date codes. The 5b is 91 for 1991, which is exactly when I would have put this since I have an I357 with ISP instructions from around then. Do you have the delay element and paper delay insulator? The white plastic looking parts I have never seen. As with all old Blue Thunder I have seen, the grains look great.

    Thanks for the reply! The delay element is stuck inside one of the red caps. No paper delay element, but lots of other small parts that might be part of that assembly. 26 years old!
