Strunal is the largest violin making company in Europe and they have been going for decades. Actually they say they can trace their history through 300 years! Here is their website
They also make violins under the brand names Dvorak and Paganini.
The 3310 (also called the S3310) comes from near the top of Strunal's Concert violin range. It is very well flamed. Omega Music had these priced at £886 and they had a reputation for very low pricing. The nearest current version is the Maestro Bologna 333W which has a list price of about £1060 (equivalent, depending on current exchange rate).
The scratches are not large and mainly only visible if you turn them to the light.
