As Jean suggested earlier, here are comparisons of the letters r and s.
(1) is English Roundhand in the style of the letter r from the 18th century "The Universal Penman".
(2) is the Engrosser's Script equivalent. It's somewhat wider, in slightly heavier weight and with a larger, more open, loop.
The second, upward hairline emerges much earlier from the downward shade.
(3) is a different form of the Copperplate r which is widely used.
(4) is the Spencerian form. From the top, the second stroke slopes down much more severely and the letter is lighter overall, with very light shading.
(5) is the letter s from the same English Roundhand (Copperplate) family as (1) Note that the terminal dot is bisected by the hairline.
(2) This s is in Engrosser's (Engraver's) script with the shading more evenly distributed from top to bottom. The dot stops short of the hairline.
(3) This is a Spencerian s. Much narrower with no shading and no terminal dot.
