Identifying an old firearm safely is important. Here are some steps I would recommend:

1. Always keep the gun pointed in a safe direction. Never point your firearm at anything you do not intend to shoot.

2. Make sure the gun is unloaded. Remove all ammunition from the chambers and cylinder. Check the barrel and all chambers and cylinders to ensure they are clear. 

3. Lock and unload or trigger lock the firearm if possible. This helps prevent the firearm from being loaded and discharged accidentally. 

4. Check that the hammer is not cocked back. The hammer should be down on an unloaded revolver. 

5. Inspect the firearm visually. Look for a manufacturer's name, logo, or other identifying markings. Note the caliber size. Check the frame and barrel material. Look for serial numbers. All of this can help identify the specific make and model. 

6. Do some research. Armed with the details from your inspection, search online or check reference books for information about possible revolvers that match. Look for photos to compare. 

7. Once identified, you can clean or store the revolver knowing its specifications. Be sure to keep it unloaded until ready to use. 

8. Consider having a professional examine the revolver. If it is in poor condition or you are unable to identify it with confidence, it is best to have a qualified gunsmith evaluate it to ensure it is safe before loading or firing. 

Safety should be your top priority here. An unidentified old firearm could potentially be dangerous if mishandled or misidentified. Take your time and follow the proper safety procedures to ensure no one is accidentally injured. Let me know if you have any other questions!
