Larry,
I hadn't thought of contacting Miroku direct, but everything I have read suggests that the data isn't available from the factory. However, for the cost of a stamp (I would e-mail but the Miroku website is in Japanese!) it would be worth asking.

With regard to SKB shotguns it wouldn't take much effort to create a second database with the data input/display screens. When I set up the data capture project for old cameras a few years ago, I had to learn two new programming languages! Fortunately things have moved on and my ISP offers a simple pick&chose front end for creating projects like this. I'll get back to you.

Just a thought: cameras made in Japan immediately after WWII were stamped 'MIOJ' (Made in occupied Japan). I wonder if there are any MIOJ-stamped Mirokus out there?

Nigel.
