Not a "vaquero". Heck man, it says it right on the side "Ruger New Model Single Six"!!!!!!
"Vaquero" is a pre-2005 fixed sight Large Frame model or post-2013 fixed sight mid-frame model (with the 2005-2013 interim filled by the "new vaquero" designation," which has since been abandoned).
There WERE Ruger Single Sixes with fixed sights in 32H&R - which were, without question, marked as "Single Six" - that were marketed as "Vaquerito," aka "little cowboy", as "vaquero" is "cowboy," but to my knowledge, there were never any 22cal Single Sixes that were ever marketed as such. And again, even though these fixed sight 32H&R Single Sixes were MARKETED as "Vaqueritos," they were never labeled as such, and forever and always have been "Single Sixes".
The small frame 32 and 22cal Ruger single action, whether fixed or adjustable sights, or the drift adjustable dovetail sights of old, are all Single Sixes, not Vaqueros. There's never been a 22caliber Vaquero. There has never been a small frame Vaquero. I don't know why that question comes up so often. A Ford Ranger could never be a Ford F-150 just because it had a different steering wheel - it's a Ford Ranger.
