Who is my Waterman?

I am still not certain what the pedigree is of either of these Waterman pens!

Word has it on FPn that the blue pen which I've had for ages is a Gentlemen's Waterman, while the small red fountain pen is a Lady Charlotte. I know I bought the Lady Charlotte at the Fountain Pen Hospital--it was on sale in one of the cases in the back of the store near the inks. It was the day I also bought my first Noodler's.
