I think 'Best' BLE is perhaps incorrect. Looks like a fairly standard BLE to me.
It looks like a very nice gun to me, as are most of the Birmingham boxlocks that I have handled. Light, responsive, durable and pretty much foolproof, if used with appropriate loads. But I agree with 300846, I think "Best BLE" is stretching it a bit.
It seems like many dealers are calling any English gun a "Best gun" now days. Marketing, I guess.
And it looks like a non-ejector (BLNE) to me, not an ejector (BLE), BTW, although I have been wrong before.
