IMO, it is the Evans version of a W&R 51/54. It is likely semi-unique to Evans. Evans ordered enough guns from W&S to get what he wanted. Evans' job was to get his customers the highest quality they could afford. I'd suggest that the valuation would be as follows. Evans is Brand Value two (BV2). The gun looks to me like a tick less than a true best work gun so Original Quality grade five and a half (OQ5 1/2). Current Condition level looks to be "significant use," so CC3. BV2-OQ5 1/2-CC3 = $4,100; considering the case, I could see this gun at $4,300.
