WTB: Mirex-tilt-shift adapter for Mamiya M645 Lenses/ Minolta-Sony Cameras- Sony a900

[Fragomeni]

I've been looking around for this piece for my Sony a900 but I've been unable to identify any retailer that carries it. If anyone has one of these that they'd be interested in selling please let me know. Also, if anyone knows of any retailers or websites that carry this please let me know that as well. If not, i'll probably just go directly through the company. Thanks!
