I just bought a kit of ring spanners from
"Alpha Tools", I think it is a low-end brand,
either that, or this particular kit was of
so-so quality, is my intuition. Anyway they are
"DIN 838". On a double open-end spanner, which
is a Heyco 10 and 13mm, it says "DIN 895".
It would be interesting to see what they say if
anyone found them on the web and care to
share...
