ruger standard auto info

[Backwoods7]

I recently traded for a ruger standard auto 22 with the red eagle grips. Nice old gun, it has a little holster wear I'd say its 85% or so. Serial#776x. Any idea what year it was made? Also how much could I expect something like this to bring? Any info on it is appreciated. Thanks for the help

That gun was made in 1950.
It is likely a "Type 3" version of the Red Eagle autos.
As with anything, condition is everything. In 85% condition, I'd think it would be worth about $300.

You've acquired a very neat older Ruger RST4. Congratulations! From what I can see from here it has the more "rectangular" shaped ejection port. Is it possible that you could post a picture of the bolt out of the pistol? Especially the front end of the bolt.
