Hey. This is my first post as I recently came into a big variety of SLR cameras, previously owned by my father who is a retired photographer. Can you advise the value of these cameras and what would be the most appropriate place to sell them? Mamiya C330 Mamiya RB67 Mamiya RZ67 PRO II Linhoff Technica Sinar P3 a couple of Nikon F3 one F90, one FE35 All of them are working, have a full set of lenses and are in excellent condition. Thank you in advance.
