Good morning. I took a .38 Special revolver to a gunsmith for some trigger work, and when I picked it up he gave me three casings from his test firing of the pistol. As I'm looking at them, I don't recognize the manufacturer. The casings are marked: 1) R A 6 7, 2) WCC 1988, and 3) W-Super-W 38 SPL + P. The +P I get but the rest of these markings are strange to me. Does anyone have any info. on these. Thanks.
