Has anyone ever seen one of these? I found this at an estate auction a few months ago and at the time I had no idea what it was. Then one pops up on ebay and it says it's a pinstriping tool for bicycle rims. Thought i'd see if anyone here has ever seen or used one before? Here are some pictures. Here is the link to the one on Ebay. http://www.ebay.com/itm/370781119784?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 Let me know what you think. It does have interchangable wheels for differnt width of pinstriping. thats what the two other wheels at the bottom are for.
