Corona - Drawing instrument Vintage

Mechanical drawing instrument “CORONA” (spirograph) – early 20th century – complete wooden set with box, original instructions and spare parts

Description
A rare and fascinating educational mechanical drawing instrument, known as 'CORONA', dating from the early decades of the 20th century.
This device was designed to produce complex geometric and ornamental drawings through a mechanical system that guides the pen on a circular base. This type of device represents a precursor to automatic drawing instruments and later spirographs, and was intended for educational and creative use.
The set is mainly made of wood, with metal mechanical components, and it includes all the main components.
Content of the set
mechanical device made of wood and metal
Original vintage nibs of various kinds.
Original spare parts included in the set.
original illustrated cardboard box.
Original instructions glued inside the box.
The presence of original spare parts and vintage nibs is an uncommon detail, considering that such components were consumables and were often missing in the surviving specimens.

Operation and use
The original instructions are printed in three languages (English, French, and Spanish), as a testament to the product's international distribution.
The operation is based on a mechanical system of rotation and guidance for the nib: by manually turning the disk and adjusting the position of the arm and the pins, the nib traces ornamental, complex, and symmetric curves. By varying the anchoring points and using different nibs, it is possible to obtain an extremely large number of different drawings.
The instructions recommend a slow and steady rotation of the mechanism and suggest using different inks to enrich the final graphic effect. The device was therefore conceived as an educational and creative tool, not as a simple toy.

Condition
Good, appropriate for the age.
The original box shows normal signs of use and wear over time. There is an ownership inscription, “Mario”, written in ink, with stroke characteristics compatible with the use of a dip pen and not with a ballpoint pen. Such markings are typical of educational objects of the era and contribute to the historical character of the set.
The mechanism appears intact and functioning.

Period
Circa 1900–1925
Dimensions
Box: about 25 × 12 cm

Note
Uncommon item, complete with its original box, trilingual instructions, and vintage spare parts. Ideal for collectors of scientific and educational instruments, designers, illustrators, and enthusiasts of historical drawing instruments.

The device was designed to produce complex geometric and ornamental drawings through a mechanical system guiding a pen nib over a circular base. This type of apparatus represents an early precursor to later automatic drawing instruments and spirographs, and was intended for educational and creative use.

Set contents
mechanical drawing device made of wood and metal
Original period pen nibs in different types.
original spare parts included
original illustrated cardboard box
original instructions glued inside the box
The presence of original spare parts and period nibs is uncommon, as these were consumable items often missing from surviving examples.

Function and use
The original instructions are printed in three languages (English, French and Spanish), indicating international distribution.
The device operates through a mechanical system of rotation and guided pen movement: by manually turning the disc and adjusting the position of the arm and anchoring points, the pen traces complex and symmetrical ornamental curves. By changing the anchoring positions and using different pen nibs, a very wide variety of designs can be produced.
The instructions recommend turning the handle slowly and evenly and suggest the use of different inks to enhance the final graphic effect. The device was therefore intended as an educational and creative instrument rather than a simple toy.

Condition
Good, consistent with age.
The original box shows normal signs of period use and wear. It bears a handwritten ownership inscription (“Mario”), executed in ink, with line characteristics consistent with the use of a dip pen rather than a ballpoint pen. Such ownership marks are typical of educational objects of the period and add to the historical character of the set.
The mechanism appears intact and functional.

Period
Circa 1900–1925
Dimensions
Box: approximately 25 × 12 cm

Notes
An uncommon and complete example, including original box, trilingual instructions and period spare parts. Particularly suitable for collectors of scientific and educational instruments, designers, illustrators and enthusiasts of historical drawing tools.
