Could be Alejandro Paul's Business Penmanship.
Quoted from MF About text

hi ryuk, thanks for your 'stubborness' :-)
it is the only sample i have, and as i said, business penmanship is really close... it is just a little lighter, and the lower case 'e' has a 'flick' that is missing on the image sample... there is also an obvious loop on the 'r', and the dot on the 'i' is hollow
There are still people who can write in Palmer style, and other variations of Spencerian Script, with such regularity that it is difficult to spot differences in repeating letter combinations. Consider the following example from the fountain pen network in 2012

Reminds me of the script taught to students in _The Palmer Method of Business Writing_ by A.N. Palmer before almost all business writing became typewritten.
