Speculation and innuendo lloyd. Only Veral really knows. Have you asked him?
I had a "purchase order" ready for years, but never pulled the trigger on LBT. I wanted one of his alloy hardness testers (before the Pencil Test), a couple of caliber lap kits, and a couple of molds. His cost put me off as much as his customer service, web site, and Order Form inaccuracies, which I attempted multiple times to alert Veral to, but always got a deaf ear. The more I read about his "customer service" (hit or miss it seemed), the less I liked LBT, although, those that hit were "sold" on the Veral magic and that in itself was magnetic...
