Hi Jim,
I throw my hat into the ring on this one - having just viewed your album.. Frankly, the stock may be problematic, as it looks as it might have been repaired? If it was, that should be checked for integrity. As well, I think it's honest use - with some traces of case left on the receiver. As well, it's also been apart at some time - when and for what reason - you and we may never know..
Anyway - if the stock has been repaired and given the condition of the wood - I'd probably "guesstimate" about $1600-$1800. If the stock isn't cracked, but again given the overall condition - I'd probably put it about $1900-$2200. Obviously - these are "ranges" based on "good" and "average" conditions of the bore, if it's on face and tight, etc......
Just my $0.00002
John
