Mr. Collward,
The Shroyer was estimated at 25-30K, $29,500.00 is hitting the mark. $12,000.00 for 10" of a original C. Hawken is pretty good also, give them $3000.00 for the front end and $9,000.00 for the 12" of original and it averages at about $750.00 per inch x 56" gives you $42,000.00 if it was all original (which is considerably inflated). I heard from a reliable source close to the estimator that these rifles had a considerable amount of restoration also, in review of the last 2 auctions and the less than desirable reputation of the collection, the little bit of info that you have produced is more positive than negative!
