It's an Ortofon moving coil cartridge and its 'Concorde' shape was used on later Ortofon fixed coil designs, which are now marketed and sold as DJ cartridges.
The MC200 came after the MC20 and MC30 designs and received mixed reviews: Martin Colloms in HiFi Choice rated it as 'average', whereas Noel Keyword in Practical Hi Fi (?) though well of it placing it alongside the likes of other MC cartridges such as Fidelity Research, Dynavector and Audio Technica. I have always wanted to try one and prefer it to both the MC20E I once had, and to the MC25FL, but IMO it's not as good as the early Ortofon MCs, or of the later SPUs.
