Ruger Single Six Frame Type?

Just acquired a single six
and by the looks of it it was produced in 1985.
Was thinking of buying some faux pearl grips and started researching the frame types of this gun model's history.
I think I have a "RED" frame. I need the Ruger experts to confirm. I'm getting confused between the xr-3 and red frame grip types.
Looks like xr-3 is vaquero and both of the grips are the same?
Look at this site:
http://www.gungear.com/ez-catalog/X300536/206/BKHAWK-PEARL
It states:Ruger Blackhawk, Vaquero and Single Six Frame
(Not the XR-3Red Frame)??? Which I don't understand

Thanks in advance

P.S. Anyone want to sell some grips PM me

I think an '85 single six will have a XRN-3RED grip frame. It should be marked on the frame under the left grip.

Hogue makes a grip for the single six. Same grip as the blackhawk. NOT the same as the super blackhawk. Hogue # 83000
