I'm sure a few others will chime in, but if complete with matching serial numbers and in excellent condition $3500+ seems to be about right. There's one on gunbroker right now for $6000 but it's been there for a long time. I recently stumbled upon mine for $1000 with a few scratches, chip out of the wood match grip, and no original box. A couple members here have suggested a vale of around $2500 given those details. These seem to be incredibly hard to value.
