From the famously series Levin produced from 1973-1979. Kind of Anniversary-series which marked that Martin Corp. newly bought the Levin plant i Gothenburg - Sweden.
The relationship with Martin is clear - a wondelfull Guitar in a high quality but to a resonable price - 6-string also known as the “Ragtime” model.
Really playable with an amazing sound - in decent shape when you take into accont that is around 50 years.
Good but worn case is included - buyer should arrange shipment.
