The Block-Notes was the first of a number of miniature strut cameras using the 4.5 x 6 cm plate size popular in the 1900s.

The Block Notes was made in four sizes:

• 4.5 x 6 cm, introduced 1902.
• 6.5 x 9 cm.
• 45 x 107 mm stereo, introduced c. 1904.
• 6 x 13 cm stereo.

A wide range of lenses was available for the smallest size. Accessories included: filters, close-up lenses, shutter release, tripod adapter, magazine changing box, roll-film back, folding view-finder, and an enlarger.

The sliding aperture is accessed from inside the camera. The dark-slides are nickel with 'ELGE' on the tabs. The price was £9.12.6.

The stereo 45 x 107 mm model was available with single plate holders or a changing box, the Newman & Guardia catalogue of 1911 lists the changing box available as an accessory having the same registration as dark slides. This seems surprising unless an intermediate frame was used to adjust the film-plane registration. The rear of the septum can be disengaged. Other accessories for the smaller size stereo are similar to those available for the mono camera. Lenses listed are, Elgé Rapid Rectilinear, f6.8 Goerz Anastigmat, f6.3 Krauss Tessar, f6.8 Hermagis Aplanostigmat.

On this model the apertures are adjusted by a sliding tab on the front of the camera, the changing box is held in place by a spring mounted plate on the box which engages a stud on the back of the camera body. The Tessar model was priced at £17.0.0.
