Herretts RNSS grips - help w/ ID?

[Tyro]

I'd picked-up a used set of Herretts grips through eBay which were described as being for an S&W K-Frame. Well they're not, so I'm going to offer them for trade. But so as not to cheat the next guy, I'm hoping to confirm which revolver they're intended for.

These look like checkered Herrett's Shooting Stars. The label states 'Model RNSS', which I've read means Ruger New Single Six.

Can anyone confirm that the RNSS model is for a Ruger Single Six?

Those grips would definitely not fit a single six, new or old model. If they are for a ruger they probably fit a speed six or service six
