Originally posted by RiceHigh I think there was no formal and exact date for the establishment. It was only a small OEM factory who made film projector elements when it was found.
Your speculative thoughts is not a conclusive answer to my question.
The company is said to have been registered in November 1919. A registration means a document with signatures and a date. As far as I know Japan, it is a well organized place, so I would be surpriced if such a document did not exist once...the question is if it still exist, and how to find out what date is on it, to find out what day in November we are going to have the
birth day party!
Now, without bothering to go through the whole article, the fact that (at least the google translation) it does not mention that Pentax was founded in November, means that it is not the "complete" Pentax history, which you claim. And of course it can't be, it is far too short for that. You would need to write a whole book. Maybe it is the best write up in Chinese, what do I know. But there was nothing in the google translation I did not know from before, and some interresting details missing. Non the less, I've saved the link.
