H J Robinson whose advert appears on the wall here, a few yards to the east of Brentford Bridge, were a long-established company in Brentford High St. According to the Brentford High Street Project entry on Number 155:
 
"Henry John Robinson, plumber, glazier & painter is listed in the 1845 directory and in 1851 he lived here, employing 4 men and 2 boys. He employed 5 men in 1861, by which time he was 61. In 1871 Mrs Caroline Robinson was running the business, employing 17 men. Henry John (presumably the son) employed 17 men & 1 boy in 1881. The business continued in his name in 1891, 1901, 1913, 1920 (when it was ‘plumber & builder & decorator’), 1928 (‘decorator’), 1933 (‘builder, decorator & contractor’ proprietor H Allen) but had closed by 1940."
 
These buildings, including two properties apparently Grade II listed at 157-158, were replaced by a modern office block around 2000.
