WTB: Lee Loader 375 H&H Magnum

Looking for a Lee Loader in 375 H&H Mag. Don't think they've been sold for a couple of decades now. Original Lee part number was 90283 as seen in the photo back in the 1960's but that part number appears to be now repurposed to a 530 ball cavity mold. New, these sets go for about $60 but are only available in limited calibres. If this is still up I'm still on the hunt.
