Hello everyone.
For my first post on papawswrench.com I would like some help in identifying who actually made this wrench, the time period it could have been produced, and the rarity of this Spanner wrench.
As mentioned above, I am unsure about who actually made this wrench. There was a Joseph Asbury, and a Jeremiah Asbury. Both made wrenches, but I am leaning towards Jeremiah Asbury on this one for some reason...
Here are the photos: (I hope to post more when my photobucket is working)

Stamped on the wrench, is "ASBURY'S - PATENT ______ SPANNER - WARRENTED", and on the handle (which twists clockwise and counter-clockwise to open the jaws) there is a stamp that reads "ASBURY'S RO NO 16685"?... The last two digits are hard to make out...
Anyways, this wrench as been plaguing me ever since I had obtained it, and I hope to find out some info about it.
Thank you,
Regards,
Dave
