The Old Stables are currently a blacksmiths / metalwork shop
Theres a 1884 datestone above the window
I’m currently unsure if they were the stables for any building in particular, the New Inn around the corner had closed by then according to the plaque.
The only structure of note on the 1894 map seems to be the coastguard station, hence the name Rocket Terrace as it was manned by the Rocket Brigade
