41-42 n suffix style

[A.Mifsin]

I posted this question in another thread, but it seems that this is a good example regarding my question, so, I am submitting it here also.
My 41-42 Luger. Has the letter suffix which looks like an N, like the Luger that Chris has, Now I know that are 41-42 Lugers with the same letter suffix like mine, but according to Mauser Parabellum 1930-1946 book, it is a P. From my photo it is clear that it is not an N but more like a P with the long leg cut off. My gun is matching and the grips are marked SE 655 on both of them, it also have the PO8 on the rear left side of the frame. Thanks for any feedback.
Alf.
