I have a Colt .45 barrel that has been in my family for at least 40+ years. It came with my dad's Series 70 Gold Cup National match that he got so long ago that he can't remember...although he remembers carrying it on patrol as a USMC MP, back in the late 60's/early 70's (Camp Pendelton and Vietnam) I no longer have the gun *sob* but, I still have the extra barrel. I would like to sell/trade it but, I am having trouble discovering it's value so, I am reaching out to this great community for assistance. It's stamped Colt 45 on top of the barrel and it has never been used so the condition is excellent. I will take photos and post later if needed. Thanks to all, in advance.
