A kit for creating a twin-lens reflex camera. It provides detailed instructions on how to use it. I wanted to build it, but somehow my enthusiasm waned. It's new and unused, but I bought it about 3 years ago and have been storing it at home, so the outer box may be slightly sun-faded. - Title: Twin-Lens Reflex Camera 35mm Film Camera Book - Size: Approximately 15cm wide x 21cm long - Contents: A book explaining how to use and enjoy twin-lens reflex cameras - Price: Original price 3500 yen Thank you for looking.
