I inherited a complete very early 1921 Colt Parts kit. All the parts are there except the receiver and barrel which were destroyed decades ago. All the parts are original as far as I can tell. I need advice from the experts on this as I have never seen a early 1921 parts kit for sale. I know the stock alone can be worth at least 4K or more, but have no idea about the value of the complete lower and bolt. I will post pictures if needed. All the parts are in excellent condition. Thank You.
