To Daxias,
       Please tell me something about the Ricoh manual camera. As you know, Ricoh manual cameras are very popular 20 year ago, I want to know something about Ricoh manual camera, if possible, would you please tell some web site, I really appreciate. Today I can not use Chinese, I am sorry to ask you to read in English.

这是在加拿大的网站.
理光在欧洲的网站,好像是英国的也有介绍,比较多内容.
理光的3PF, 还是很实用的.

It seems to me that Ricoh has given up his film based camera production. That is why it is not easy to find information on the web. Any way, you can find some thing here:

It might not be what you really wanted, but it is quite similar.
