1958 catalog which is what bill showed shows 6 in adj wrench which I don't think mine had in it. I'm planning to add the 3/4 wood chisel
and a 1/2 in cold chisel. That leaves one small clip which might house a center punch as Les suggested but I can't find a photo of this chest to verify this' Think it could be in 1960's but can't find catalog covering this era.
