Hello,
Been lurking on this site for years. TC does make a Left Hand Thumbhole stock. I know because I have one. As far as I know they only make it in Laminated. I too was told there was no such thing. While at the local Gun store up the street, the owner showed me a right hand thumbhole Omega. I told him I was left Handed and he said we have one of those too. To my amazement he had 2. My friend and I both bought one. This was 2 years ago. Also I have seen 1 or 2 on Gunbroker.com. Everywhere I went I was told there was no such animal. TC's FAQ a year or so back even said there were none. Good luck finding one. I have no idea how many were actually made. They're worth it if you find one. I love my TH Omega and my X7
