Scott asked:

Does anybody know a resource where I can get another one? I doubt
EBay would have something like this.

Au contraire mon ami...I got a C model Dash1, early (Non-LES) and late
E model Dash 1, even got an E Dash 34 via eBay.

BTW your post title has TCTO in it, is there some specific Time
Compliance Tech Order (TCTO) you're looking for or simply any E Dash
1?
