Your Chiefs Special Airweight is from the mid to late 1960’s. The grips sound aftermarket and may have been made in Mexico ( typically stamped with the country of origin on the back). If the grips are what I think they are, they generally sell for around $150 by themselves. FYI, you could put period correct S&W Magna stocks on the gun for around $25.
This model was offered with 2” and 3” barrels, in nickel or blue and with a round or square butt grip frame. The value depends mostly on the condition, but the configuration may come into play. One in nice shape is worth in the neighborhood of $325-$400 around here, a bit more if as new in the box with all the original goodies. Dont forget about your potential grip value. Photos are important!
Frankly, if it came from a dear friend, I would think the sentimental value would far exceed the few hundred dollars you’d get selling it.
