Welcome to DRTV, quite a great piece of Colt's history. Still a shooter only gives credit to its quality.
Keep it oiled, stick with standard load ammo, do not refinish it, and hand it down to your kids/grandkids. it will continue to work for another 100 years with routine use and maint.
Thanks for the pic. Send the specs to Colt, they are some of the best in archived pistol data/ history. May be able to tell you something about it you may not have known..
