MORRIS, I just seen one a few days ago on one of my gun sites in box and with both cylinders. sorry can't recall which because I have 3-4 on my favorites list. I also own a colt trooper .22 mk. 111 4"barrel in bx. and appears unfired. I will put it on the sale market later this month. you are correct about trying to find info. on this mod. they just for what ever reason are hard to find on the web.
