Rollei 35 was selling well and all of the production of amateur cameras had been transferred to Singapore, there was insufficient work to keep the enormous workforce busy. Consequently, after a long and draw-out start-up phase, contracts to manufacture on behalf of third-parties were accepted from 1979. When Rollei Deutschland filed for bankruptcy in 1981, Rollei camera products still accounted for 97% of the production capacity in Singapore, which meant that the factory had to close. USH (United Scientific Holdings – see New owners) established a new company called Rolloptik Ltd. in order to purchase and store the plant and machinery. This would make it possible to restart production in Asia later on should this be necessary. Voigtländer The Braunschweig-based camera manufacturer Voigtländer closed down on 23 August 1971, whereupon the German mail-order firm Quelle GmbH (Foto-Quelle) entered into take-over negotiations, but no agreement could be reached. In the end, Voigtländer's assets were divided according to a scheme devised by Peesel: Rollei, Carl Zeiss and the state of Niedersachsen would each receive one third shares with Rollei retaining exclusive rights to its brand names. As a result, a new company called Optische Werke Voigtländer was established on 1 March 1972 with 320 employees to manufacture lenses for both Rollei and Zeiss Ikon cameras. In addition, Rollei took on 300 former Voigtländer employees. After Zeiss Ikon stopped making cameras in 1972, the company Voigtländer Vertriebsgesellschaft mbH was established in 1974 purely to sell cameras. There was, however, no clear distinction between Voigtländer and Rollei cameras, and many models were sold under both brand names. This even applied to 35 mm SLR cameras, whereby their common lens mount was now referred to as the Rollei/Voigtländer bayonet. Although the trade press regarded the takeover as a long overdue consolidation of the camera industry in Braunschweig, the merger made no sense from a business perspective; from it Rollei gained neither new products nor new customers, nor did it have any use for the additional production capacity and employees it acquired – all the more because the factory in Singapore was under-utilised. 1975 to 1981 - Peperzak / Wehling / Porst era Downsizing the company On 26 August 1974, after Rollei made a loss of 37 million DM on revenue of just 137 million DM, Peesel left the company "by mutual agreement". At this point Rollei's debts amounted to around 500 million DM, which meant
