I'm looking for information on reproducing proper Artillery Primer packs. I have one PDF of the Frankford label and have seen a few photos of surviving packs and general dimensions.

What I really need to know is how the packs were milled. Were they solid pine with five holes bored in them, was there a channel cut for the priming wires to lay in, etc?

Does anyone have any good information?

I'd love to make some Confederate packs too if there is any good info on those.

Our unit's focus is the Eastern theater. Any help would be greatly appreciated.
