http://i222.photobucket.com/albums/dd3/buswrench/york-2012/Y12-0013-23.jpg looks like #17 in this group,
any idea on value? rarity?
Craig
The wrences pictured were in one of Bus Haury's auctions, he might know how rare and valuable that one is.
It is #557 in Schulz, with no note about rarity.
That's a nice collection of unusual wrences.
More photos!
Not super rare, or valuable, EG , you won't retire if you sell it, but worth more than a run of the mill monkey wrench.....
