Is anyone familiar withe the "Waller Precision Engineering" 7 1/4" wheel quartering jig please? I have found one in the workshop of a recently deceased friend. It is still in its wooden box, and in mint condition. However, there are no instructions. I can guess how to use it, but it is to be sold, and I would like to include some guidance on how to use it. Also, how old might it be? I've tried "Google", without result. Thanks
Regards Maurice
