1900s, vintage cameras are predominantly the folding type constructed of wood, metal parts are usually brass -occasionally nickel plated and bellows are often fashionably maroon in colour.
Prior to this, antique cameras in the 19th century were also mostly of wood , quite often lacquered rather than covered in leather, the early bellows types often had square cut corners - see 'bellows cameras'.
The earliest cameras, say 1850s to 1860s, were often formed by two rigid boxes, one inside the other, unfortunately the LICM currently has no examples.
