If you give a more detailed description or some photos I'll give you a valuation. My valuation system uses Brand Value (BV), Original Quality Grade (OQ), and Current Condition (CC). Greener is BV2. If we can get to an estimate of OQ and CC I can use a look-up table for a value estimate. Greener guns spanned the full range of "milord's best work guns" to "keeper's/farmer's guns" for OQ. CC is all about the use and care the gun got.
