Sorry - just noticed the alert. They're all Ed Browns, and all of these are chambered in .45 ACP. Top left is a Kobra Carry (4.25"), and is the first Brown I owned. Grips are from Grips by Esmeralda Top right is a Kobra (5"). This gun was a gift from my wife for our 11th ('Steel') Anniversary. Grips by Esmeralda. Middle left is an Executive Elite model (5"), Centennial Edition. It has 'Centennial Edition' roll mark on the slide, a special serial number featuring John Moses Browning's initials, and also has 'JMB' on the barrel bushing. The grips are legal ivory. Middle right and bottom are both Executive Carry models. The bobtailed one is blued, and also has Grips by Esmeralda. Both have crowned barrels, recessed slide stop pins, and carry cuts (Hi-Power cuts). The SS one also has a flattened and serrated slide, and the rear of the slide checkered. I'm sorry, I don't recall where I got those grips. Since this picture was taken, I've also picked up a Brown Kobra CCO LW. 4.25" slide on an aluminum alloy Officer sized frame, chambered in 9 mm. It matches the other two Kobras in color and grips. All of my 1911's have a .156" u-notch rear sight and gold bead front sight.
