Ahh thanks. I cannot seem to find any mossys with a HS with adapter riveted or spot welded to it. Just HS alone. So I should have clarified that point.
I finally got a 4/19 HS Bayo adaptor attached to a win 1200 barrel thats been collecting dust at a friends shop for 20+ years in the back. no "W" marking, but I do not see rivets securing HS to the BA, just what I would call spot welds. Were all WIN made adaptors riveted or was that limited to the 6/29 adaptors?
If win didn't make it, I wonder who was making them 20+ years ago.
Thanks, I'll get some pics up in a bit
