More food for thought ...
Rather than my transferring every one BigCy's surperb photos, quick-click back to Page 11 - Post # 1051/52. Notice how well everything seems to fit. Now take a close look at the backside image where you will see those two pressed indentations that look like a couple of small golf clubs. I've been wondering about those and can't recall if they have ever been focused on or discussed? They were intentional when manufactured, and must serve a purpose. I'm thinking along the lines of one of two things, and possibly both.
1. To add structural strength to the item?
2. To raise the backside slightly away from whatever it was attached to so as to
allow the rivet to spin freely.
If you look at the one image, you will notice that the "heads" of the golf clubs fall in line right where the wire crosses. Or, if the item happened to be attached to something like a sheet of tin, the golf club impressions would serve the same purpose of keeping the backside slightly away from the tin.
One more thought ...
Regarding the mesh-wire idea again, if the two longer tabs were tucked into the wire first, and the bendable tabs second, the entire thing would be "securely attached" and ready for whatever purpose it served.
Bottom Line _______ ?
Attached to > WIRE or TIN ?
