Jay,

I reviewed the most likely places to find this type of joint -castle framing. The roofs have castles have full hip or pyramid roofs, and in many locations these are the places you will find the dragon beam. I do not find this...



Strahl in use in construction must be some obscure reference, this is not a usual word, and your use here confuses me.

As it realates to German and Swiss forms,

again, it doesn't. It may be found here and there, but if so finds its way here from French sources and is not an important part of the German or Swiss traditions.
