Which carbine are you talking about Bill?
Mine or the rock ola? I found mine at a show that had about 20 tables.
It was so dirty it looked like it sat since WWII.
The grease on the slide was so dry it took over a second for the action to close from the bolt being locked back. I do remember the rockola being talked about before and itbwas the carbine I was talking about in mine original post when I said I had seen others like it. I also remember a few loose flip sights over the last few years being modified like that.
Thanks for your compliment on it being nice.
Dave
