I couldn't find anything online, you can only find photos of them once open and dried but all cones have this one period when they are mature but unopened, how do they look like ? Any wild seed collectors here?
Google is your friend. Plenty of photos of baby cones to fully opened ones. You would probably want them at least matured, but not necessarily open. These like many other pine cones will close up with rain. Your illustration shows a more exaggerated triangular form when it's more egg like in my experience.
I've tried searching Google but didn't really find just the premature one , also I don't know if their form changes but the illustration shows 1:1 exactly how the cones look where I'm from

My parents garden has them all the time and they look like the one in the bottom right of your added picture
This webpage is as good as you're going to get. There a picture of cone development over 2 years. https://landscapeplants.oregonstate.edu/plants/pinus-sylvestris
