I've recently launched my crossbow-making business, called The Modern Armbruster:
http://themodernarmbruster.com
My aim here is to design and build crossbows that are as close as possible to their historical counterparts, while using some modern materials and tools to keep the costs down a bit.
Currently I have two late 16th/early 17th century German sporting bows in stock; one is in cherry, the other in walnut, and both with accents in curly maple. The triggers are of a German style from that period (i.e. gun-style as opposed to lever), with a simplified locking mechanism. The prods of both are aluminum alloy, with Dacron strings, and pull about 70lbs at 11.5 inches of draw (8.5 inch power stroke). There's more details on the web site.
I'll be putting up some new models available in due course, but in the meantime I thought I'd share these pics of the two in stock!
