It appears to be German built/sold LeFaucheux actioned gun with back action locks, and laminated barrels. It was, when new, a fairly high Original Quality grade gun. Brand Value would run low as Lustmann is not a well known name. Current Condition doesn't appear to be very good at this time.

So lets make the following assumptions pending more information. BV is level five (BV5 = unknown Continental maker). OQ is grade five (OQ5 = very good quality hammergun and top quality BLE). Current Condition is level eight (CC8 = marginaly shootable, requires extensive repairs).

BV5-OQ5-CC* = $150.
