What's the difference between the M600 blue and the M605 blue models? Richard Binder's site has a picture of the M600 and I like the look of the pen, but the M605 on Pam's site looks a slightly different shade of blue but that could just be the lighting.

the M600 blue will actually be striated blue, with a black cap, and gold trim

the M605 is a lighter blue, solid blue with an ink window, and rhodium trim.

Richard has full pics of three M6xx pens. the middle pen is M605

Thanks! That answers my question. I didn't realize the solid blue in Richard's picture was the M605.
