Hi,
Yes is the AoiArt tachi, luckily, by chance I found it in their online archive before the sale, it is listed there at 4.2m yen, Pete's page has it at 3.2m and 'HOLD' so Aoi dropped a million yen! The koshirae is certainly late and may be Meiji. Also very luckily Del Mar only discovered the Kageyori was a juto on the morning of the sale, too late to tell anybody.
I haven't posted any images as I can't better AoiArt's.
In the same sale I bought a Gassan Sadakatsu, also originally from Aoi, see below:
