The small priming horn filled with ffff powder was first used in 1930 because it is not historical.He also states that the 'short starter' has no historical context because none have ever been found
So you have a lot of advice about that particular book's paraphrased statement. Folks have not pointed out what a lot of us understand as obvious, and authors often omit the obvious as well...., here's what I would "understand" from whatever the author wrote that you paraphrased...,
The small priming horn filled with ffff powder was first used in 1930 because it is not historical. [as far as the author knows at the time of publishing] ..., the 'short starter' has no historical context [in the flintlock era] because none have ever been found [so far as folks know.... at the time the book was published].
Books are "static". What is published is frozen, while history and archaeology are not static in that more information comes to light as time passes, and further, old information gets re-interpreted. Alas sometimes, especially these days, folks re-interpret a LOT of history with a political agenda, which to my opinion is actually skewing the information rather than helping..., but that's for another thread in a different area of the forum.
But things thought wrong were later found to be correct. Two examples:
"Yellow was not color fast so yellow clothing faded over time" (Then why was it used in the Maryland flags over time? Flags fly during the daylight right?) They found some colorfast yellow dyes, available in Maryland made from vegetable materials and so the conclusion changed.
"The twisted wire two-tined fork isn't authentic as very few have ever been found" (Until somebody unearthed a large pile of the things at an historic site..., probably a box or bag of the things got dropped and covered by the mud).... conclusion changed.
The other thing to remember is there is a HUGE HUGE difference between "it's not Historically Correct" compared to "do you guys use X item".
For example. So far there is no accepted bullet board from the AWI or before. I use one anyway, AND although it is sacrilege to some..., I use it when I talk to tourists at historic events. It does a great job of holding a patched ball so the tourist can see what is meant when I explain how the rifle works to be so accurate over such a long distance AND it also illustrates to them as I explain that...,
..., the bullet board is NOT historical..., but it could be.... the tech was there, and there was nothing else needed, BUT we have never found any even though they are a good idea, but they are also wood and could've been damaged over time, but still, some we think should've survived, so even though we think it's obvious, sometimes folks just didn't invent the obvious. However, somebody could, tomorrow, find a bunch of them and voila, we'd change our conclusion...
So you can use something that's not right, if you place it in the right context.
