They are all sizes from the little boxes that shear keys came in up to the ones that are about 4" x 4" x 2". I bought out a dealer about 10 years ago. There were many boxes with one little part in them. When I found others of the same part number, I consolidated them into one box for each part numbers. I must have gotten 10,000 or more NOS B&S, Clinton, Kohler, Onan, Tecumseh, and Wisconsin parts. If I had been 2 weeks sooner, I would have gotten all the Bolens stuff including cans of Bolens paint.
I am not going to spend time inventorying the boxes. I thought that somone might have a use for them. It has just seemed to be a shame to put them in recycling. I've offered them before. Time is running out. Good Luck, Rick
