I went to a yard sale today, and asked this man if he had any old cameras. He told me he does and said he could bring them tomorrow. One of them he said was given to him in the 60's when he was in the service, and said it's a rangefinder he called a Robin made in Japan. I googled it to no avail, and am wondering if anyone has heard of a "Robin". I'd like to know something about it before going tomorrow. He did describe others that sound like the Argus "brick", so I'll probably get one of those. Thank you, Russell.
