when did the firstfrontier man add a cape to his riflemans shirt. We don’t THINK they were used in the Fand I but were common fifteen years later. When was it first used? Who can say it’s too early?
Do we have middle nineteenth century loading manuals that tell us how to use a block?
None that I know of. Yet there they are in photos.
I agree with Carbon 6 that they were simple tools and were probably invented fairly early.
I don’t take one to a colonial period event. Not because I don’t think they could have been used but because they raise eyebrows.
