Good day. This is Jeff Dowell. Ted Dowell son. I live in Bend OR, work out of his old shop regularly (though not on knives, just handicraft stuff) and provide daily care and company to my mom (Ted's widow), Betty.
There's lots of great info about this particular era of knife that's already been provided by those above. That said, for the past few years I have putting together what I hope will become the definitive website on Dad and his work. It will be launched in roughly 45-60 days at:
www.tmdknives.com There is a 'placeholder' home page at that address now. Once launched, one will be able to determine almost all the info you are seeking on this particular knife from a digital catalog archives of every TMD Catalog ever produced, as well as their accompanying price lists. A pictorial library of many of his most elaborate art pieces that he produced. All magazine articles ever written and published on dad, all TMD newsletters ever created and sent out, etc.
I'll post here again once it is up and running. And thank you, to everyone who has posted the kind words and comments of appreciation for his work.
JD
