| + | The '''Foth Derby''' was a strut folding viewfinder camera for [[127 film]] rolls, made by [[Foth]] from 1931 to 1943. It had a [[focal plane shutter]]. The earliest examples took 24×36mm pictures, but the format was soon switched to 3×4cm. Some later variants had a coupled [[rangefinder]]. |

| − | ==History==
| |
| − | Designed in 1930, the [[Foth]] "Derby" was intended as a low-cost alternative to the [[Leica]] and [[Contax]] cameras that had come on the market. The German-designed Derby was a strut folding viewfinder camera for [[127 film]] rolls, made by [[Foth]] from 1931 to about 1940. The Derby sported a cloth [[focal plane shutter]] capable of shutter speeds of 1/500th of second. It was marketed as a vest-pocket camera suitable for action photography. The first versions of the camera had a film gate size of 24 × 36mm (akin to the 35mm format of the [[Leica|Leicas]]), while all later versions used the full 30 × 40mm format the 127 film format was capable of without a need to change the lens.
| |
| − | | |
| − | ==Identifying your Foth Derby==
| |
| − | The Foth Derby comes in a bewildering range of variants. In total five discrete types can be distinguished, each with their own sub-types, lens combinations and viewfinder options, augmented by additional variations subject to the market the camera was sold to. The technical and construction details common to all Derby models are:
| |
| − | *Cloth focal plane shutter with speed settings of B, 1/25, 1/50, 1/75, 1/100, 1/200, and 1/500.
| |
| − | *Leather-covered aluminium body construction, with a strut folding system.
| |
| − | *Lens with helical focussing.
| |
| − | The [[Derby_ID_key|dichotomous key]] provided [[Derby_ID_key|here]] provides an avenue at identifying the types.<ref>The typology set out in this study was created by observation of a large number of Derby cameras in the author’s collection</ref> The cameras were sold both to the continental markets (with distance scales in metres) and to the British and North-American markets (with distance scales in feet). The final incarnation of the camera design is the full aluminium model, the readily identifiable French-made [[Gallus]] [[Derby-Lux and Derlux]].
| |
| − | | |
| − | ===Original Model numbers===
| |
| − | A perusal of the historic literature shows that Foth does not seem to have distinguished between the models with different gate sizes (24x36mm and 30x40mm). A reference in an instruction booklet refers to [[Derby#Derby type 3 (1935–1939)|Derby Type 3]] as ‘Mod[ell] II’ <ref> Directions for using Forth-Derby-Camera 3x4 cm with Focal Plane Shutter up to 1/500 sec. Anastigmatic Lens 1: 3,5 or 1:2,5 Automatic Self Timer. Printed in Germany [No date],</ref>, and a 1936 advert by the German photographic dealer Wauckosin (Frankfurt am Main) refers to a Derby II as the new improved model.<ref> Advertisement: “Derby II das neue vervollkommnete Model. Wauckosin & Co. , Frankfurt am Main, Kaiserstraße 50.”</ref> On the other hand, a brochure put out by Burleigh Brooks Inc (New York, selling the coupled [[rangefinder]] version ([[Derby#Derby type 4 (1936–1940)|Derby Type 4]]) refers to that as the ‘Model II”, while the other (clearly a Type 3) is labelled “Standard Model.”<ref> Brochure: Forth Derby Cameras. Standard Model. Model II with American Made coupled range finder. Burleigh Brooks, New York </ref>
| |
| − | | |
| − | ===Serial numbers===
| |
| − | The later units of the Foth Derby cameras can be uniquely identified by the serial number of their [[Derby#Lenses|lenses]], the early units do not carry any serial numbers at all. Careful inspection will reveal the presence of [[Derby_production_codes|manufacturing codes]], which most likely represent the staff codes of the individuals who machined and assembled the lenses and camera bodies (see here for a [[Derby_production_codes|guide on how to locate these codes]]).

| − | The early models of the Forth Derby and of the Foth-Flex do not carry lens serial numbers. The first serial numbers occur with the introduction of the second model Foth-Flex as well as the Forth Derby 2B. The observed serial numbers for the Foth-Flex fall into the range of 10,000 to 30,000 (10169 lowest and 26640 highest recorded number). Foth Derby lenses seem to follow-on in the sequence and fall into the range from 35,000 to 87,000 (35,036 lowest and 86,753 highest recorded number). Unlike with the Forth-Flex, where the runs of the f2.5/75 and f3.5/75 lenses seem to be discrete (with numbers over 20,000 reserved for f2.5/75), the f2.5/50 and f3.5/50 lenses mounted on the Derby seem to be part of the same run, apparently with no differentiation in the numbering scheme.
