There is a Japanese version of the Bygrave/MHR1 position line slide rule up for auction on eBay with a seller in Sandy Eggo, CA, USA.
I'm not affiliated with the seller at all and the price is well above what I can afford, but thought I'd share in case there is interest. There aren't very many among us who know how to use one and I hope that it finds a home where it's history would be appreciated.
