There was a name plate on the back of yours, but it is missing. Your camera could be an Okuhara, as it is very similar to the 4 Okuhara cameras that I have seen pictured on the Web and the one that I own. However, it is not identical, although all of the Okuharas I have seen pictured are different. The main difference is that none of the others has the wooden ground glass protector.
Your camera is probably half-plate (4.75 x 6.5 inches ), not 5x7.
I do not know how old the cameras are. I emailed the library in Osaka, and they searched a number of business directories from the early 20th century for me, but they could not find any information on the Okuhara Camera Mfg. Co., Ltd. There were a number of companies that made similar cameras, including Chartan and Tanakaichi Seisakujo (Tokyo Daito). It looks like someone was making and wholesaling the metal fittings (supports, clips, tripod turntable, etc.) and a number of small shops (possibly woodworkers) were building the cameras with these parts and putting their own label on them. The same parts could have been making it to India, also.
My camera is pictured at

Please let us know if you can find more information about the Okuhara cameras.

Edit -- Your camera has a metal "arrow" plate on the side of the back, like the Chartan pictured in a camera history book from the George Eastman House (I don't have the reference handy, unfortunately). None of the Okuharas I have seen have this arrow.
