Ok. I have uploaded a couple of photos. On the right side of the barrel it is engraved "Made in West Germany." On the left side the barrel is engraved "Beck Single Action .22 L.R. Cal" It has three symbols engraved on the left side of the receiver (one says 67 in a shield, one is a crosshatched shield and the top one is some unknown icon) and of course it has the serial number on the left frame and on the underside of the barrel. I have owned this since about 1967 and have put a couple thousand rounds through it. The barrel looks like new inside. The bluing is rubbed off about 1/4 inch by 1/8 inch on the left tip of the barrel, and a little thin line of bluing rub on the cylinder front edge, both areas probably from holstering it. The grips are original (plastic) and there is no rust in or on it.
It is fairly accurate and has never misfired.
