Hello Erik & Madskp, I do own two of these Passives, the one that is with me (in storage) is 204957XX and has no button or external LED.
The other one is staying with my father in law, I will try not to forget to check its numbers next time I am over.

My only accessible Passive is Type No 1657 with SW1.4. It does have the switch and the serial number is 162812XX.
Also, I think that the SW versions may have similarity with BL Active - i.e needs SW1.5 for A.AUX and SW1.6 for MLGW compatibility (There's probably SW version details in one of the archived forums)

Another source for narrowing down when the button and LED was removed is to do an Ebay search for Beolink Passive and ML/MCL converter. A lot of sellers have pictures that show both the front and the sticker with the serial number.
