Unfortunately I can’t help you determine if it is a N-7 but I can say say what a hell of a find - the details are fantastic on the coin. Your soil is definitely forgiving. Good luck with your hunts. Walt
I do not think it is a N.7 but will look and let you know shortly, however, the bleeding stars are known as flowlines, happens, not sure how often but it is a known feature. Looks like a N.10, which is known to have those flowlines.
