Re Camberley Inquiry
I have a pair of the brown Camberley as pictured in your post. Very nice, elegant pair of shoes. Can be worn with suits, and looks outstanding with casual wear (jeans/slacks, etc). When worn with a suit, the bottom buckle shows in a way which is not at all overly conspicuous.
It is obviously very similar to the brown Hallam in the front though the dainite sole makes it a bit more comfortable and perhaps a little bit more substantial-looking. If you are familiar with the 348 last, are comfortable with its length, and and like it, I think it is a nice buy. Note however that the instep is a bit tight. To the extent that you have a high instep, this may not be a good model for you. Cheers.
