Help me ID these Vintage Tonearms?

[drastronaut]

Good afternoon! I grabbed some random hifi parts in a box at a garage sale. Found these two cool tonearms, with cartridges, that were difficult to identify. The first is an Audax and the second is a bang and Olufsen with an add counterweight. Seems like it might be a 1959 era ST/M model but I can’t seem to find concrete info on it. Any help on id’ing these is very appreciated!

In case of the B&O , the cartridge type# should be between the four pins. Once you have that , finding which tonearm it was paired with would be easier.

Thanks! This is what I see, it doesn’t have any markings. Does this mean the cartridge is a replacement non-b&o? It seems to resemble the sp1 or sp2 but I’m unsure.

The cantilever end is upturned so my guess it is a SP6 or higher version . SP1/2 had straight cantilevers . There were no copies of B&O cartridges, whatever it is , it is an original.
