Friends wrench

[jimwrench]

 A friend dropped this wrench off yesterday for identification. No makers stamping. Only marks are a small 13 stamped in both body and moveable jaw.
Certainly looks like item 52 in Vern Nails auction of 2007. That wrench is described by Bus as unmarked.
Anyone have any further info on this one ?

Jim,

I have, or have had, some like that. It seems that I remember them being stamped Germany.
