Blowback semi-automatic, with fixed exposed 4.75" barrel. Receiver tubular, with round bolt. There is a 9-shot detachable magazine. Sights are fixed. Finish blued. Black hard rubber grips on this first model feature a red Ruger eagle or hawk medallion on the left side. Approximately 25,600 manufactured before Alexander Sturm's death in 1951, but this model may be seen as high as 35000 serial number range. Because variations of this model exist, an expert opinion should be sought before a final price is established. Note: Factory verified plated pistols will bring between $2,500 and $5,000 depending on condition. Approximately 890 pistols were shipped in a wooden "salt cod" box. Add a premium of $3,000 if NIB; $1,000 to $2,000 if good to excellent condition.
