Hi cross65.
Bently was a brand name used by St. Louis Music on entry to medium level guitars imported from 1979 to 1998. The overwhelming majority of these instruments were built in Asia (mostly Korea I think), interesting you got one from Romania. In 1998 SLM discontinued the Bently line and replaced it with the Austin line of guitars.
I don't know what model of guitar you have based on the number you have provided, but I can tell you the guitars are not worth much.
Here's an entry level classical that sold for $30
If your guitar is a western model, it's probably valued in the $50-$100 range depending on the quality of the model.
