Wanted: TG5 or TG6 Olympus housing dead or alive

What I'd like to find is an unwanted back half of an Olympus PT-058 or PT-059 plastic underwater housing.

I'm trying to adapt and AOI viewfinder to another housing and wish I had the little grooved rails that the viewfinder snaps onto, if that makes any sense.

If the housing is otherwise damaged or unusable, it doesn't matter.

Let me know if you have one.

Thanks,

Tom
