I imagine these stables were down the very narrow entry just past the last shop on the left going up Rhos Road. This entry used to bend around to the left and exited into Everard Road to the left of the Fruit and Veg shop.
If this is correct, I knew Alf Davies because that entry and the one I used every day, through a tunnel just up Everard Road on the right, backed on to each other.
When I just saw this sad thread a minute or two ago, I thought "Alf Davies. No that cannot be him----he was an old man when I knew him." He must have died many, many years ago.
But----- I suppose when you are about ten years old, a twenty one year old is an "old man."
