WISI antenna on '71 280 SL

[blairwag]

Well, after rerading all the posts, here and (finally) at www.pagoda113.com, I finally began to understand what's going on. So, I rushed home from work, hoping my car's antenna might be an automatic Hirschman, just stuck. So I ran over looking for the "h" on the top cap, and on the trim ring. Well, much to my surprise, I did NOT see an "h". Instead, I saw the insignia:  "WISI".  Then it finally dawned on me what that little key is, in the small bag, with the owner's manual. Its a key to this antenna.
Unfortunately,this thing looks like a manual antenna :-(
Has anyone else every heard of such an antenna? I'm thinking it came with the car initially. Is that possible?
the car has a Becker Europa MB radio.
I don't have the original data card for the car. My Dad originally purchased this from a retnal company in Philadelphia PA,USA; and they didn't have the original data card. Perhaps I'll mail or fax DiamlerChrystler for it.
Anyone else have any thoughts?

Wisi is the manufacturer of antennas typically found on Gullwings. Drop an e-mail to the Gullwing Group for confirmation. You might also want to consider contacting Gullwing resto shops for more info (shops like Paul Russell or Hjeltness).
