Hmmm this is odd. I know it can take many months for him to fill an order. I have a friend who ordered a set and waited nearly 8 months for his, and when they finally came he was told to "never order any again" because he too was worried over time and made many efforts to contact Tom.
I tried to tour Names Unlimited a few years ago, he declined due to "trade secrets and living a hermit-like existance" but the shop is only 20 minutes south of me in Caledonia, Ohio... maybe soon i'll swing by just to see if they are still around
