Does the brand value still hold the same weight on a trade built box lock such as this?

I understand the BV rating if this was a shop built AH rifle, however is there any consideration for a gun carrying an upper level makers name that was not actually made by that maker?

Is there any way to quantify this phenomenon which was quite common in the British gun trade? Or does it even matter?
