Brian, can I suggest that you take a look at the Hull local studies collection of photographs. They can be found at http://prismdata.hullcc.gov.uk/gallery/albums.php There is several photos there of Osborne Street, including one with no 87 which is noted as "No.87 is Mrs. Annie Sliw grocer". There is also one showing the 8 houses and 5 privies in Appleyards Building. Regards Keith D.
