These three small vintage wrenches would be perfect as part of an industrial display. One is labelled "Dreadnaught" (best name ever?), made in Canada by Molybdenum, size 7/16. The middle wrench has a faint number which I believe reads ?/32. The top wrench is completely unmarked. These wrenches are small enough to be part of a shadowbox, measuring between 10.7cm (4.25") and 13cm (5").
