 Similar to Rogers,Printz & Co. Arpeco wrench shown in Cope

i  recently  sold an unbranded one of these on ebay.  simple but brilliant  design.
i have seen a full chrome one.unbranded also.

 Heres a similar design in a English wrench by Hill & Griffith. Stamped (Made in England) is only marking.

There is a loop over the last 'o', I think It may say 'standard'...

(which would be odd if it's german, unless it's export...)

See FitZall/Standard wrench & Tool co, Alloy Artifacts:http://home.comcast.net/~alloy-artifacts/Photos/tools/standard_wrench_adj_wedge_fitzall_pat_f_cropped_inset2.jpg

I have a similar one with no makings.

Having done considerable research on the Long patent sliding wedge wrench. the rogers printz & co wrenchs were all mad in USA and the production and trade mark(Fitzall) went to Standard wrench and tool co in ca 1912. The wrench marked in Germany came in at least 4 sizes with several different markings.  The ones stamped Standard in script both on fixed jaw(illegible and on the sleeve (nice and clear) are stamped made in Germany very small on the bottom edge of the handle.  SUL is another common marking (Germany) and the company is still in business making locks.  Most if not all made in Germany are made to the Bohn/Werner patent of 1924.
