Breck: the person (who also posted on Shotgun World but refused to identify himself) who posted that blog borrowed the explanation and images from my PictureTrail (now defunct
) and website (which costs me money to maintain), linked earlier. I got many of my images from gentleman here, or had to find them on the internet, and early on didn't do a great job of documenting the sources. Many contributors asked to remain anonymous.
An attribution would have been nice, but I'm not selling anything, and the information is free.
