We have 2 Wrenches vintage items.  They are on the smaller side measuring about 3 3/8" in L x about 7/8" across the widest point outside measurement (1/2" inside) on the silver one open end.  The 2nd one is closed on the end and measures about 3 3/4" in L x about 7/8" across the circular end and 1/2" inside the square.  They both have rust on them - the closed wrench is covered in rust.  They both stick to a magnet.
