Box Hook Latch

I needed a clasp/latch for some boxes I was making and was not impressed with the flimsy tin ones online so designed this. It is approx. 50mm high and 26mm wide and is in 3 parts. The hook must be attached to the swivel base with a small screw, not sure of the size...#2 or #3 I think. I plan to finish these to look like antique brass.
