Fuzzy photos, but it's the unmarked design attributable to S&L -- the same type found on the Lüdenscheid sample boards and in the S&L salesman case.
It's also the type for which there are a small handful of examples marked "100" or "65" on the pin, but neither W&L nor K&Q were prolific KM makers like S&L...
They're pretty common and in my opinion must be accompanied by the same controversy that dogs all S&L zincers -- the dilemma of late wartime vs. post-war assembly.
