I found an old camera in my grandparents home as we were sorting through their estate. It appears to be a Japanese camera. A "moving" camera (not snapshots).
??There is no name on it (at least that I can read), although there is some writing in Japanese (but I do not know Japanese!). It is numbered. It is in a "box" that has an opening door, where the writing also is. It is extremely heavy!
Can anybody tell me what type of camera this is or what it might be called? I do not even know how to do a google search because I do not know the proper name. Please forgive my ignorance; I love photography but this is a little out of my area of knowledge!
Thank you for any help.
