I have two of them. One is the "regular" 1.125" barreled .22LR, and the other is a 2.5" barreled 1860 "Sheriff" model in .22WMR. The first came with the birdshead stocks, which were later swapped out for engraved boot stocks from NAA. The second came with smooth boots, and those were swapped out for genuine elk stags, also from NAA.
I've been carrying the first one in my jeans watch pocket, turned around (I'm left-handed) so it can be hidden behind my belt-worn cellphone case. It's been riding lately as a third, and may possibly be a second if I ever decide to ditch belt carry of my primary (my LCP-MAX was bought with that possibility in mind.)
I saw those CH-ed ones online a while back and was thinking they're pretty handsome. Nice catch.
