From reading Talk:Archer from what Doneve has said about the Archer being introduced in 2458 and not 2474 is what I have placed here. If this is wrong, I can delete it to make it right. DerangedShadow 20:07, 21 July 2012 (PDT)

I believe that the primitive Archer, the first version, was introduced in 2458, while the ARC-2R is 2474. At least, that makes the most sense to me. --Scaletail 07:26, 22 July 2012 (PDT)
With the release of Experimental Technical Readout: Primitives, Volume 5 this is correct, with the 2458 version being now known as the ARC-1A. Cheers.Thehawk (talk) 13:04, 29 July 2017 (EDT)
