Hello, firstly I apologise for making this my first post. I've been trying to identify this item for a,most a week now and all the facebook groups I'm in have had guesses but couldn't give me a definitive identification. So i thought I would try the experts! Guesses so far are shutter peg, a tine guard for some kind of machinery, oh and some kind of ground peg for marking areas with string... Thanks for taking a look.
