My only experience with Volquartsen is the two Volquartsen rifles I own, one in .22lr and one in .17HM2. My opinion of Volquartsen is very high based on these two rifles. I'd say that if the rest of the rifle will be silver then the trigger guard would probably look better in silver also.
Full stocks are desirable and it's only property to use as needed. If selling is what's needed then it's fulfilling it's purpose. I think that sounds like a fair price.
