In the 3 or 4 days that I've been fighting with myself over whether I want to bid on this or not I've done a lot of observing of it. So, a rambly discourse on some of the speculations/educated guesses based on those observations are, it left the factory as a standard 56SB Renegade. Along the way whether they Johnny Cash'd it or did it all at once, it had the factory markings removed except for the serial#, the barrel was browned & dovetailed and the long Hawken sight installed, the front sight modified to look more traditional, more traditional looking thimbles were installed as well as a nose cap, triggerguard, and the brass buttplate. the 56SB was added to denote caliber. and at this point it was likely considered 'done'. But then they decided to send it to be rebored/rifled and it now sports a 58cal RB rifled bore.
