The X300s-330x-370s etc was being made by Shanghai Optical for Minolta, and then for KM. It was mainly sold in developing markets and China. Shanghai is part-owned by Konica Minolta and from the 1970s onwards bought, or was sent, the tools and jigs for discontinued cameras and lenses. The Dynax 5, 4, 60, 40 were all made in Malaysia as was the 7 (at least initially) and that plant continued working during Konica-Minolta times. There was some talk of the Malaysian plant being a buy-out or third party investment opportunity, or ceasing to exists. I know that I have not seen Malaysia stickers on anything new or Sony - just Japan and China.
At the time, I was told new factories were being built as Sony estimated their sales would be anything up to ten times those of Min/KM and the Malaysian plant was simply not big enough.
At the time when Sony took over, the only film cameras being made were the Dynax 40 and 60 and all other production space was occupied with the D7D and D5D. They had stopped making the Dynax 7 and 9 entirely as far as I know - the 9 earlier than the 7.
