Primus Ferire
Attenuator with male-female connectors that are not SMA, they’re just slightly larger and the genders are reversed, the markings in full are: S/M 980-0000-08-.5 DB 15786 SOCN 308939-18-D TYPE TSM PLUG/JACK ATTENUATOR. I’m going to guess this is an individually calibrated attenuator of 8dB plus whatever increment is discovered in testing, good to 18GHz. New.

What stands out about the front layout is the Trueline brand sitting just above the input jack.
