Flatbed negative scanner (East Killara)

Hi, this may be a long shot. I'm looking for a flatbed scanner that can scan different size negatives. There are dedicated slide and 35mm film scanners but these cannot scan the larger negative film sizes such as those for Kodak box cameras and twins lens reflex cameras. I have 35mm film negatives, slides, and larger negatives to scan. Flatbed negative scanners can handle different sizes. If anyone has such a scanner they no longer need I will be happy to receive it. Cheers, Jim (East Killara)
