Later this week I am picking up a Police Positive Target 32 about 85%, serial number 132577 and was wondering when the approximate date of manufacture was on this little sweetie. I am anxious to give it a good cleaning and oiling and shoot it. Are these fairly common in 32? I was told that they felt there were more of the 22 WRFs made. Thanks in advance. P.S. Second Colt this year, I may be getting converted.
