My new Soho Reflex has no lens at the moment, the first has a TT&H Cooke-Butcher f4.5 Anastigmat 67/8" lens, which will be a Cooke Series II. It's possible it's the original lens, aside from being manufacturer Wm Butcher was also a wholesale company.
Kershaw who made the Soho reflex were distributed by Marion & Co, until a number of companies merged to form APM in 1921, and also became shareholders in Thornton Pickard. The photographic film and paper sides of the companies Marion, Paget, & Rajar (in Mobberly) later split from APM and merged with Ilford in 1929. The Rajar site is now the location of Harman Technology, Ilford.
Both my Soho Reflex cameras have Marion & Co badge plate, but they were sold as The Ross Standard Reflex, and also as Beck, & Fallowfield, reflex cameras.
In 1921 a 5x4 Marion Soho Reflex was £43 10s 6d, the extra 4 way front swing f5 9s so my first Soho camera would have been £48 19s new without a lens, adding a Cooke Series II f4.5 lens, twhich £12 14s 6d, the total without a lens boardwould be around £51 13s 6d
By 1934 and the depression prices had droped around 10%, a 5x4 Ross Standard Reflex with an Xpres f3.5 lens was around £46 6s , a Soho Reflex with a Cooke Series II f4.5 lens £46 15s, or with the Cooke Series X f2.5 £70 10s, in comparison a 5x4 TP Ruby reflex was closer to half the price with an f4.5 lens. At the same time a Rolleiflex with an f3.8 Tessar was £22 10s, a Leica III with 50mm f3.5 Elmar £25.
1934 was also a year of change with the introductionofthe first the first Exacta taking 127 film, the Soho Precision Camera, also sold my Hugo Meyer and Porst as the Silar. and made by Perka who also sold under their own name - the company going bankrupt and asets and tooling purchased by Linhof, the camera becoming the first Technika.
I will take some photos later tonight, unless I did someyears ago when I bought the camera. By chance I have found a PDF file on them I downloaded in 2013, it's an updated Shutterbug article from a few years aearlier, the last page is from an Australian camera repairer and gives good instructions.
