Olbia pseudo TLR

The Olbia 6x6 pseudo TLR is an Omega Eikon with a better Gitzo shutter. This can be demonstrated by the fact that the 'Olbia' Label riveted on top of the viewfinder covers up the 'Omega' brand markings which are embossed into the viewfinder lid.[1] Apparently the Swiss watch manufacturer Omega objected to the use of the name, forcing the proprietors to change their branding.[2] The Olbia 6x6 is a pseudo TLR, sporting a large Brilliant finder that projects a mirror imaged view. The camera body is made of Bakelite with a folding metal viewfinder cover and a metal back. The camera takes 620 film.

The following models and variants are known (for completeness sake the Omega Eikon is also included here).

The metal lid shows an embossed embossed 'Omega'. The Bakelite body bears the name "Eikon" below the taking lens.[3]
