Thank you for the add! I'm a photographer, but new to Rolleiflex. My fil gave me a 2.8D that was a work horse for my husband's grandfather. It appears to be in great shape, but needs to be cleaned. It's filthy! Any recommendations about how to start cleaning? The user's manual suggests a camel hair brush or doeskin - neither of which I own in 2020. A normal dust blower isn't enough. I would prefer to do at least some of it myself and not send it out at this point. Many thanks! I'm anxious to get it cleaned and, hopefully, up and running!
