I need some help, on this gun. I have a S&W Bodyguard Model 49 no-dash, serial is 495064, the gun is blue an in a solid 90% plus condition. It also has diamond grips, the gun is all original. Do the diamond grips make this more collectible? How old is it, and whats it worth? I know pictures would be more helpful, but I am unable to post them at this time. Any input would be very helpful.
