I work on some concrete pumps full of Walterscheid hose ends requiring up to a 65mm wrench. The little bit of searching I did DIN 894 is a German standard for open end wrenches. Work has some stamped made in India that may or may not be there when you need them though they are still in decent shape after 200 pound gorillas have put 4' pipes on them. I'm thinking brand might not be that important with them. E-bay is full of DIN 894 wrenches are there any to avoid or ones to go after? Geodore, Stahwille, Elora, WGB, and Hazet are all common on e-bay along with a bunch of made in west Germany. There's also a bunch of no name wrenches, many of which the chrome is coming off of that I'm not sure if they are worth the gamble.
Buying one at a time looks like the best way to get a decent quality set from 36mm to 65mm. I'm having a hard time convincing myself to buy combo wrenches to go this big when the DIN wrenches are much cheaper and work well with a pipe when necessary.
