what is the vaule of this gun and how to dissemble one to be clean
You need to realize that all you have given us is the fact that your handgun was made by the Colt's Patent Fire Arms Manufacturing Company. Colt's made many, many different guns over many years, beginning in the first half of the 19th Century clear up until the present time.
You will need to be a lot more specific about your gun before we will be able to help you.
The name of the company has changed a few times and the one plus you have given us is that this is a relatively early name. It is entirely possible your gun was made in the 19th Century.
At a minimum, I suggest you post the serial number and several clear photographs of your gun. Then we can probably help.

Reggie - you have posted in another person's old thread and we have no idea what you want to know. If you are looking for information about a firearm, please start your own new thread with your questions. Post the make and model name, the complete serial number and several clear photos. Thank you.
