Michael,
To use RM's spreadsheet you would need to determine the Current Condition (CC) of the gun(s). If you assume a gun has to be sleeved for safety reasons, then the CC would be 8 or 9 (marginally shootable or wall hanger). After sleeving, it would be a 6 or 7 (note: the spreadsheet doesn't have a sleeving category, but does show barrel replacement).
Very marginal to unsafe Boss Best SLE: BV1-OQ1-CC8=$3876
Sleeved Boss Best SLE: BV1-OQ1-CC6=$8874
I'm sure RM may say I misinterpreted the spreadsheet, but the key is to determine the Original Quality of the guns (in this example).
