Can any one help with a date of manufacture or approx. value of a Ruger pistol? On the left side it says: Ruger 22 Cal. Long Rifle, Automatic Pistol. On the right side it says: Sturm Ruger & Co., Southport, Conn. USA, with the serial number 224227. It does not say Mark ...
Thank you.

It sounds like you have a Standard. If it has a 4.5" barrel it's an RST4, if it has a 6" barrel it's an RST6. Value very much depends on condition which is impossible to assess without detailed pictures.
