I stumbled onto the frame and thought it was interesting. While reseaching discovered that it was spec'd with the revolvers, and a largely M900 kit. I had both lying around without a home so I picked it up.
The original spec included a zoom stem, black zoom bar and silver uno post. It came to me with the black KHS stem, so I'm using a silver Tioga bar and black Tioga post for now. I'll probably keep an eye out for the zoom bits as the stock set up was pretty unique..
