The 'tabulator' model is quite common here in the UK, and dates from the early 1980's. The Yugoslav factory wasn't actually owned by Olympia, they sub-contracted manufacture. Having said that, there was no quality difference between German and Yugoslav Travellers - at least initially. Up to about 1979, the Traveller was only available from Olympia dealers but after that it was mass-marketed through non-typewriter outlets. A 'general purpose' English language keyboard was introduced and then the pre-set tabulator. Although the machine was still streets ahead of the competition in quality, economies were made in construction as the years went on. They probably finished around 1989. The sub-contractors got permission from Olympia to continue making the Traveller under their own name - mainly for Eastern Europe and often with Cyrillic keyboards, but production ended completely after a few more years.
