I have a Model 647 LNIB, fired 6 times, with an 8 and 3/8 inch barrel..it has been a safe queen since I fired it and now it is time to sell it for something I would use more..any idea as to it's worth here in CALIF?..thanks in advance for any and all info..all5x

I would think that something north of $650 and I presume you still have the box and the paperwork!
They've reintroduced the PC version again but you don't see many of the original 647's currently.
