Kem1988, I sorta invented this system of valuation as a short cut compared to the handling of thousands of gun as needed to develop intuitive understanding of values. I did a market research project based mostly on auction results to determine what factors were the major influence on value. It boiled down to name brand for Brand Value (BV), Original Quality (OQ) of the gun as made, and Current Condition (CC).
Boss, H&H, Purdey, and Woodward are BV1.
Westley Ricahrds, Dickson, Rigby, Grant , Beesley, Powell, Atkin, Churchill, Henry, Lancaster, Evans, Watson, Wilks, Greener, Boswell, Gibbs, and Lang are BV2.
All the rest of the brand names will value at BV3.
Do note that the name brand does not determine OQ. Gun makers made and/or sold a wide range of quality grades as needed to satisfy their paying customers. Boss, possibly, made and sold only best work SLE's. On the other hand, it should be no surprise to find a best work gun from any of the BV3 makers.
Does that answer your question or are you asking why Charles Hellis is BV3? I have a good explanation but it takes a bit of time. If you wish to discuss it, post back and I'll post it.
Hope this helps and that we can fully answer your questions.
