The confusion about the Iowa/Van Dorn flag is due to me.
My faulty "research" years ago (more wishful than methodical!) led to my concluding that the Van Dorn flag at the Iowa archives was the flag of the 43rd MS.
It is not.
It is almost certainly the flag of the 40th MS.
I am deeply sorry that my juvenile mistake has led others astray!
However, I am almost beside myself wanting to get a copy of that data sheet for the actual battleflag of the 43rd MS, drawn by the immortal H.M. Madaus!
Tom! Please send us a link, post it somewhere, or email a copy to me at huffman1234@bellsouth.net, as I have been researching this unit for nearly twenty years now, and I simply must have a reproduction made of this flag!!! (And you know the fellow I'm likely to ask to make it!)
Thanks! -- Jim Huffman, 43rd MS Infantry
