Clearance of SBRs/ Trappers|Winchester Rifles|Forum|Winchester Collector

Have read some previous posts where some members/guests on the forum submitted SBRs/Trappers for authentication/originality were approved and others were not as is to be expected. 

From reading the details regarding the specific configurations for each however, all seemed to have met the definitive requirements for said authentication?

As stated from the responses from those individuals whose rifle configurations were denied, seemed to indicate it was possibly contingent upon who performed the evaluation?

Also, appeared there was no recourse for petitioning a negative evaluation?

Your collective take on this?
