Justin,
The early snap -locks were called just that, snaplock or tinder lock.
As Dale says, the tinder was a one shot deal most likely, renewed after each shot.
I believe that the normal practice was to carry a thick matchcord, very often wound aroundnthe left arm, and lit.
This was used to light the tinder.
Early locks (1500-1520-40) were very small, and would not take a thick matchcord.
Rich,
No, the intent of the tinder in this case was not to take a spark. It has to be lit, and holds a good very hot cone-shaped coal for igniting the pan powder.
In this detail from the battle of Pavia, (1525) you see both the tinder And the matchcord used to light it.
I must just add that I believe each individual would carry his own matchcord for lighting tinder.
This is apparently the conclusion Michael's research lead him to.
Logically, in a battle I can't really imagine being without a personal source to light my tinder. No time to scurry around looking for the bloke with the matchcord.
"Where's Albert?!"..............."Oh, he got chopped!" .............".I guess were all screwed then!" kind of thing. :-)
