Definitely the real deal - newer production, but same chain pattern/design:

Newer production as well, but oddly enough, 8-speed compatible. I've never seen SACHS 8-speed, so I wouldn't know if cog spacing or chain width differs from the 7-speed stuff, although I'd take a guess it is (either that, or it is the same stuff, marketed as 8-speed chain in an effort to convince folks to buy new chains when they converted to 8-speed, tagging along on the Shimano 7/8 speed chain requirement hype):

Thanks Kurt. that seller had no idea if it would work (i asked him), but I'll try and get it per your recommendation. There was also an older Sedisport that went too high for me earlier this week.
The Sachs that I have is a 7 speed, very similar to the regina 7 speed s of the mid 80s, and the same width - about 2-3mm wider than a 6 speed ORO.
What is a "ramped" freewheel? Is the shimano UG such a thing or is it somthing else. Or is it one of those with the cog teeth all lined up neatly (something that cannot be done with threeaded cogs)???
