I thought I’d mention that I got the incorrect version in the mail, and I’m not too regretful about it because it’s a nice little level. The package was filthy and opened, but no big deal. One thing that I just noticed, however, is that the level has “Made in W. Germany” embossed on it. That puts its mold before reunification in 1990, although it could have been cast after that. So, hopefully any correct versions we find will likewise be authentic to the era rather than a later revision.
Also, mine has measurements in inches, instead of metric, so they were made for both systems.
