The Brand Value of the name Purdey (BV1) has the effect of doubling the value compared to a Hussey (BV3) named gun, Original Quality grade for OQ grade and Current Condition level for CC level. Both the Husey and the Purdey (SLE's both) should be considered OQ1 (best work level). I'm not clear on the CC's as it stands. Bad barrels on the Purdey are a big hit. Poorly done replacement barrels on the Hussey would also be a big hit. Are the replacement barrels by Hussey? Are they best work barrels? Worst case on repair of the Purdey barrels would be Teague lining at about $2500 to make a shooter and $20,000 for new barrels to maintain value. The Teague lining is a big value hit compared to OE barrels.
