Hell to all,

I need some help identifying the model and age of a Smith and Wesson revolver.

Please look at the photos below. ( I can take more photos if needed )

Is this a pre model 10 ? There is no model number on the indie of the frame ( see photo ) just the number 5 and a faint 7. The serial number on the bottom of the barrel matches the serial number on the butt.

Thanks in advance for any help/ info you guys can provide.

Best regards,
Danny
