I bought a pair of used 7 string pickups, vendor said they're from 7321/7421 series but I can't determine what type or year. They're direct mount style 4 conductor, the part number tag says PTP4240 for the bridge and PTP4021 for the neck. The official Hoshino parts lookup page doesn't return any results, I browsed all four pages of their pickup part numbers and nothing is close even as a partial.
Anyone have an idea of what these could be?
