I am working on the assumption that a Photoweigh machine was installed on or near Brighton’s Palace Pier, (England) sometime in the early or mid 1930s.
HISTORICAL BACKGROUND AND CONTEXT
Anatol Josepho, the inventor of the first automated photobooth, opened his “Photomaton Studio” in New York City in September 1925. In March 1927, Josepho sold the rights of the Photomaton process to Henry Morgenthau’s business consortium.
By the end of 1927, a British investor group purchased rights to distribute the Photomaton in Europe and Canada.
In 1928, Josepho sold the European rights for the Photomaton to an English/French consortium.
The Photomaton Parent Corporation Limited was set up by Clarence Hatry in 1928 to operate automated photograph machines in hundreds of public places such as railway stations and amusement parks.

I presume that by 1930, the novelty of the coin-operated photobooth had waned and that entrepreneurs were looking for a novelty or gimmicky variation on the self-operated portrait photo booth. Someone came up with the idea of a “Photoweigh” machine, a piece of apparatus, which took a photographic portrait of a customer as he or she sat on a weighing machine. The resulting photo strip would give details of the weight of the sitter as well as displaying the usual photographic portrait.
The earliest evidence I have found of an apparatus in England that took a small photographic portrait, while recording the weight of the sitter, is a photo of a bespectacled man wearing a trilby hat, with a tobacco pipe clamped between his lips. According to the printed display, the photograph was taken on 29th October 1931 at Selfridges Department Store, London. The photobooth photo (below) was sold on eBay in May 2014 for £10.50, (US $17.85). This early example does not carry the trademark of Photoweigh Limited.

Photoweigh Ltd. is mentioned as a recently established business in the 1933 edition of the British Journal of Photography. A firm called the American Automatic Photoweigh Company Inc. was listed in the American State of Delaware in 1934.
The 1933 edition (Volume 80) of the British Journal of Photography lists Photoweigh Limited as a recently registered company (viz. ” Photoweigh. Ltd. (276,512). — Private company. Registered June 1. Capital, £5,000, in 4,000 5% redeemable non-cumulative preference shares of £1, and 20,000 ordinary shares of 1s. each. Objects: to carry on the business of manufacturers and dealers in optical, scientific, photographic and industrial instruments, cinematograph and other films, projectors, cameras and magic lanterns, etc.”).
Presumably, Photoweigh Ltd. set up a booth near or on Brighton’s Palace Pier between June 1933 and 1938.
In his 1938 novel “Brighton Rock“, the writer Graham Green mentions the Photoweigh kiosk being located in the tunnel under the Palace Pier in “the noisiest, lowest, cheapest section of Brighton’s amusements”.
A Photoweigh booth (owned in the 1960s and early 1970s by George Keeble) was situated on Brighton’s Palace Pier until 1972.

I very recently received a Photoweigh photo from Clifford Groves of Brighton. (Above) The photograph was taken in 1964. Cliff Groves explained the circumstances in which it was taken.
”I am the good looking one on the right, the other chap is Gil Tipping – a good friend of mine still after 50 years. We were both working the summer season on the Palace Pier, in the “Palace of Fun”. There were no gaming machines only what we called “gaffs”. These were very similar to fairground stalls. Gil was running a bingo stall and I was on air rifles. The mods and rockers were creating havoc on the seafront the day the smudge (photo) was taken and it was
(as the Chinese say) an interesting time – battles galore!
