Hi Jeanie,
I can’t help you with the Post Office Hotel it was in Hulme, Manchester not Stockport.
I have found a little bit of info regarding the Moss Rose, Travis Brow.
It was a beer house in 1853 and closed in 1971. It was thought to be a venue for gardeners from the nearby Moss Rose Lodge. When it closed in 1971 the licence was transferred to the Moss Rose in Didsbury.
I haven’t been up that way in years and can’t swear to it but I seem to remember that most of the buildings on Travis Brow were demolished when the Motorway was being built.
There is a photograph of the pub taken in 1971 advertising Hydes Beer and you can find it on the Stockport Images Archive website just put Travis Brow in the search box.
