@Matchlock: Tank you for the pictures of the cranequins from Churburg!
Strong reflex bows are indeed the fastest ones! But Iīm very much impressed that bows with thick cross sections, like the ones from the late 15th century shown in the last few posts can endure such a strong reflex. The material of bows with high cross sections is really much stressed. (Thatīs also the reason why english warbows with thick cross sections usually were made of yew wood.)
I have found one more wooden stock probably made of oak wood on the internet today. It was probably made in the 15th century and it is exposed in Hambourg. The trigger mechanism is very simple because the string is released with a "Zapfenschloss".
