I went around the old electronic store again to search for old data.
This is what I got.
Unfortunately, with the exception of page 2 and some parts, it was about other switches (lighting switches).
Anyway, I hope this will help you edit wiki.
It's very difficult, but if possible, I'll try to find more resources.
I'm sorry this isn't a scanned data (as was the previous Alps).
It's probably the last piece of data left. It was very hard to get.
Non-damaging scans use special equipment and are very expensive. I entrust this to a professional scanning firm. But I couldn't scan this because of lack of budget. I'm sorry.
Ps. I asked for an old catalog search for an unknown little black Alps switch. Maybe I can get information. I'm will excited if the older Alps catalog comes out.
