Hi guys just thought I'd drop in on this conversation as I own a so called 'prototype' Moho frames. I bought it in 2004 from the old owner of windwave. As soon as I figure out how to upload a picture from my iPad I'll add some pics.
It does have the bump stop and it does not have disc mounts on the rear, I do however have the disc mount adapter fitted that I was lucky to find on eBay. Not sure how old it is, is there a way of telling?
