I bought this one last week for exactly the same price. A worn old war horse with a rack number (stamped on the frame under the cylinder) so it must have been a security company issue gun. This one dates to 1955 and grips are original.
Bore and charge holes clean as a whistle and, although I haven't been to the range yet, I'm sure it shoots just fine. I carried a 1965 version as my duty weapon for 17 years until I retired it in favor of a stainless version, model 64, which I carried for the next 13 years. I gave mine to my son some time ago and missed it so I picked up this one for old times sake
They are great guns...enjoy!
