You bring up a great question!

I've been curious about this myself. Just stumbled across your thread while googling info about the 1040 vs. 1041. Have not seen much discussion regarding the use of the 1041 or the two books you mentioned.

I was not aware of The Errant Sovereign's Handbook, sounds interesting. Found a pdf copy at Bill Thornton's site http://www.1215.org/lawnotes/soverei...n-handbook.pdf

Thanks for your post. Maybe this bump will stir some feedback.
