Fichtel Sachs Shocks/strut Identification

Hello
I have a pair of Fichtel Sachs shocks I acquired as part of a large parts purchase. I don't know their application though. The shocks are green in color with a white label. P/Ns aren't very clear. There are a series of numbers the 1st appearing to be "BZ17-188", next "05240010-149" and "225774". There is a ferruled fitting at the bottom of the shock for what I assume is a remote reservoir? The guy I purchased the lot from had an M coupe. He doesn't know if the shocks came off the vehicle. I'm trying to determine what they're worth and if I can use them on one of my many car projects. A picture is attached.. Thanks in advance.
