I have never seen so many big bore rifles at one auction, especially Hollands. Three, Holland Eights, an H&H double four bore, a few .577 doubles, a pair of Rodda four bores...
I don't think it is in the sellers best interest to sell all of these at one auction, but then again it may precipitate a buyer get a good deal.
