Dan, thanks for repeating David's post. You're right... David's link led to the current Schneider archives.
This archive link does not have appear to all of the same material that was on the "old" Schneider site. Conspicuously missing is the serial-number/date list and data on the 1980's-era Symmar-S MC series. Also missing is the handy reference table of what size caps fit which objectives... a topic that seems to come up in this and other forums on a regular basis.
Other than that, this archive is wonderful and seems to have some archive material that I haven't previously known to exist. I only wish my knowledge of the German language was better.
