I’ll answer but I am afraid I don’t know much that can help you. I can tell you that the one in the image I sent you in email and shown in the discussion regarding the tin or copper plate on the bottom of a Bormann:
http://bulletandshell.com/forum/index.php?topic=650.15was found in Sharpsburg, Georgia which is southwest of Atlanta.
As to quantities of the different types of fuse marks I don’t know a reference with that type of information. Possibly some of the hard core students of ACW artillery have collected some data in this area that would give some indication of how plentiful they are but I've not heard of it and Chuck Jones didn't discuss it. You see the different varieties and combinations of markings and it would be nice to see in a book all the possibilities. I've seen a handful at least with the arrow. There is also the ones with the US and with stars of various configs. If you look at the last image of the images I started this discussion with you'll see one that has both the arrow and the star where mine only has the arrow. So any type of count would be complex.
Another thing that might skew the data is usable examples to determine if they are marked. A significant number of the fuses corrode to be unreadable. It could be that the mixture of the metal used at one foundry to make the unmarked ones corrodes easier and faster thus making the marked oned seem more prevalent than they were. Or vice versa. Or no impact at all.
In general I'd say most are unmarked and a significant percentage of them have some sort of marking. But I can't venture a guess and will leave that to those far more knowledgable.
