There are lots of useful information on the site which includes lots of internal material. The following link includes the lens data sheet in the late 60s:

Anyone know anything about the 40/1.7?
As in, only in a fixed lens camera?

Thanks Calvin, I'll have to keep an eye out for a non functional unit.
I wish there were more fast 40-45's out there.

Thanks for the site link!
Very interesting especially the lens information. Several questions were answered.
It seems that quite a few of the Petri lenses were indeed in-house designs. That answers some questions of origins
But some also seem to be from Sun, that I have not seen I'd before.
Sun branded primes of the 1960's aren't that common so I am sure we have seen plenty of these that have not been correctly identified.
And the company that owned the Kyoei Acall name was Kyogo Optical. A starting point for other inquiries I think. Kyoei was another brand, not the original company name.

The Acall brand is own by Kyoei Optical Co.. A Japanese site mentioned the Kyoei Optical Co.(å”æ „å…‰å¦) was established by the ex-employee of Sankyo Kohki(三å”光機), some of the design drawing and parts and were stolen the factory of Sankyo Kohki during the labor dispute. There are other source mentioned the two company are partners.

This 55 / 1.8 lens really is one of the best std lenses that I've got, I expected nothing more than mediocrity when I bought this camera and lens in a box full of stuff from a charity shop, but I was wrong. And the camera looks very good as well, maybe not 'exceptional' but up there with Pentax, Canon and the other big manufacturers.
