I do not, but years before the 2013 and, to the best of my knowledge years before any representation of any type of BR version, best guess ‘90-‘91
When this took place, my understanding was the BR-50 was in discussion….not offered yet.
Action, I believe, was not nickel plated but hardened electroless nickel …..was harder than case colored.
This I know because when they came they had the action clamp screws plus a 4-40 set screw that indexed on a barrel flat…..which was glued.
Mine snapped and I had a high end machine shop locally that could only get it out using EDM and then new tap to clean it up. Tool and die guy indicated it was some hard stuff.

Thank you. I'd think it might have been '91, as the earliest 2013 receivers were blued. The advertisement of a nickel finish suggests to me these were production rifles, not prototypes.

Regarding the tuner/tube/weight, I'm not surprised it was considered a tuner. The thicker clamping section is unusually long for an extension tube. Anschutz supplied slip-on weights with the 20xx position rifles, so my first thought is that the heavier tube isn't just for mass/balance as extra rings could do that. At the time Anschutz wete developing the 2013, they were arguably at their peak, having dominated the smallbore world (outside the USSR) for twenty years, and I think wanted the 2013 to be the ultimate 3P rifle.
