Islamic Crossbow?

[B.I]

hi aqtai,
i have found a copy of this book and will look into it. do you remember the nature of the image, ie were they modern depictions, or period manuscripts?
rick,
unfortunately, any archeology evidence from crusader sites may yield crossbow bolts, but from which side? i know the europeans had crossbows, and i have no doubt the muslims may have used captured weapons, if they were an 'advanced' technology that they deemed useful.
however, i am after a crossbow definately made by a muslim hand. the examples in existence are of complete form, but the speculation and debate is whether they were made by muslims, of just a variation of the german design.
still much appreciated and please carry on
