TESINMA Share Company: http://www.tesinma.com.er/
The only buses positivily identified with TESINMA bodywork are the seven urban buses built for Asmara Bus, delivered in March 2004. These were BMC buses from Turkey assembled in Eritrea and adapted to Asmara Bus' wishes. The company website shows also a small picture of a regional bus which resembles the standard older models seen in Ethiopia and Eritrea but is is not clear whether other buses have been built. TESINMA is an industrial company, the buses were only a minor activity.
Most likely TESINMA in Eritrea is a division/partner of TESINMA GmbH in Germany:
