Hallo,
eine kleine Anekdote was man heute alles im Internet herausfinden und rückverfolgen kann.
Einst stieß ich auf dieses exotische Gepräge:

Great Britain, London, Brentford Market, James Sutton, Merchant Market Token, by R. Neal, Percival Street E C, London, ca. 1900-1970 AD.,
One Shilling Iron Token (22-31 mm / 4,91 g), oval,
Obv.: JAMES / SUTTON / R. NEAL / 49 [& 50 PERCIVAL] ST E C / BRENTFORD Mkt: .
Rev.: 1 S / R. NEAL - 49 & 50 / MAKER - PERCIVAL St / E. C , .
Dann fand ich über Suchmaschinen dies:
Brentford is a suburban area of the London Borough of Hounslow at the confluence of the River Thames and the River Brent in West London, situated 8 miles (12.9 km) west south-west of Charing Cross.
In the late 19th century market gardeners set up stalls in the roadway north of Kew bridge, causing such traffic congestion that in 1893 the local board bought 2 a. of the Gunnersbury House estate for a market, which opened on the north side of Chiswick High Road in 1893. A large building of yellow brick with terracotta dressings was built in 1905, after the site had been extended, and, as Brentford Market, remained in use until 1974, when the traders moved to Southall. In 1980 the former covered market served as a skateboard park.
Brentford, as the name suggests, was built on a fording point on the River Brent. The town is named as Bregentforda at the time of the Council of Brentford 781 and as 'Bregentforda' and 'Brentforda' in the Anglo-Saxon Chronicle of 1016. The root 'Bregent-', naming the river is thought to originate from the name of the Celtic goddess 'Brigantia', tutelary goddess of the Brigantes tribe (whose territory was considered to be 150 miles north of Brentford, though the cult of the goddess spread across a wide area of Europe.)
The settlement pre-dates the Roman occupation of Britain, and thus pre-dates the founding of London itself.
R. Neal was an English token maker in 19 Percival St., London. They put their advertising or "maker's mark" on the obverse and reverse of tokens that they made. Percival Street (London) is located in the borough of Islington.
Nun aber der Höhepunkt des unverhofften Auffindens: Ein Foto des Marktstandes von "James Sutton and Son" auf dem Brentford Market (zweiter Laden von links, Bild ggf. mit Strg+ im Browser vergrößern):
