Hope I'm, not harping on here, but if you have a grid, you may as well make use of it.
Third horizontal line down from the handle, follow it to the right, you cross 6 vertical lines and nearly get to the 7th to get to the limb.
Following to the left, it's just
over 7 lines.
please ignore me if I'm being a bore here...
