It is Buckingham, the photo is shown here:

Looks like his VC may be at the regimental museum:

Its interesting to see that at one point he was engaged in recruiting which presumably explains the favours worn on his cap in one photo of him.
Maybe whoever owns the VC can afford to pay that kind of money for a modern copy of a photo that pops up on a few sites on the web where any unscrupulous pauper can filch a copy. Or maybe the VC came with the photo.(I am open to correction re. the item sold actually having dry ink, it could well be far older than it appears on my screens).
