I have been looking at this thread and trying to sort out what is being presented.

Pete, from what I can see on my tired old Portuguese Royal Navy, the "MP" is cojoined on the right leg of the "M".

For the life of me, I can't see the "long rope" difference. I have been studying the images for a couple of days and there is nothing in the photos shown that, to me, offer any differences in the "RP" images that can't be attributed to wear/damage/corrosion and differing camera angles.

The crossbar on the anchor is segmented and depending on the crispness of the photo and the angle observed, it may seem to be varying in the photos presented. I think they are all pretty much the same in the examples shown. If there is any question about a Luger under consideration for purchase, a crisp photo of the chamber marking of that Luger would be much more beneficial than second guessing whether it is right or wrong based on other examples.
