Information request: Unidentified Photographer

[Nigel H. Russell]

This photograph has been consigned to the November 13th Photographs sale at Heritage Auctions but I can't get a positive ID on the photographer.  Any leads would be appreciated.

Two Boys, English, late 1850's, albumen print, inscribed in pencil on verso “Possibly Winfield”, 268 x 214mm. Sheet size 505 x 343mm.  The Winfield in the inscription probably refers to David Wilkie Wynfield (1837–1887) but this image does not seem to match his oeuvre.
