Daytonas had a variety of different make wrenches in the tool kits. It seems that the set consists of 7 open-end wrenches in combinations from 6 x 7 mm, to 20 x 22. "Everest" which was made in India (as seen here) seems to have been the most common. Also found in tool kits are "Poly tools" from Italy and "Gedore" from Germany.
