Just don’t give up, when I bought mine, NOS, the seller said it was a underwhelming torch that sat in his office desk since 2012. He had forgotten about it until his recent retirement. Got it at a extremely fair price too. I made well over 75 inquiries to locate one. And,it was located through a forum where flashlights are not really the main topic.
The TCR-1 is well worth the search and all of the ” no’s ” received from asking and looking around. It’s in my pocket everyday.
Good luck on your search
