Help figuring out the make/brand of my cartridge

Hi All,

I just bought an original gyrodec w/ a Zeta tonearm(very highly used). It is probably pretty old(more than 25 years). It came with a cartridge which is black, and has a decorative design in gold with a large "V" underneath, also in gold. The cart appears to made of plastic/ebonite. Anyone got any ideas?

Thanks in advance!!
You are correct!!! It appears to be the Talisman Boron that I have. Thanks so much for your time!!! Much appreciated.!!!
