I received an e-mail request, from my web-site, for 130 of one of my truck transmission tools; which seemed really odd based on my market.  George answered with the above address and said that he was a "contracrot" also suspect.   I told him that he would have to make a cleared pre payment for materials and outside costs before I started to manufacture this many of one item.   My specialized market turns over very slowly; so I have a modes inventory. I am guessing that he was going to try to "prepay freight scam" as Sue mentioned.   So far he has not offered to make this prepayment to me.
