How did you find it, did you see a board pointing down a lane from the main road? Or did you turn off, following a sign to a village, hoping to find a pub there?
If it wasn't too far off your route back to Stockport, as you say, how about following your route on an Ordnance Survey map - you can do this on Bing Maps in Ordnance Survey view - on which pubs are marked with PH or a blue pint glass with a handle.
Then you search online for any for any you find, with a rough location.
Most pubs have their own web pages these days, with photos of them. Or there are sites such as Beer In The Evening that list pubs in an area. Just do a search for 'pubs near xxx', lots of sites come up. If these don't have a photo of the pub, you can do an image search online.
P.S. Those lime walls might have been repainted since 2015.
P.P.S. The pub might have closed down since 2015!
