Looks really old. The holes are asymmetrical, as you can see, and there's an extra hole drilled. To me it looks a bit like the TRC on Jeff's 4005. Any idea what model it came off of, or possible age?
Yes, that looks like a 60,s TRC Ilan and it probably never fitted that well looking at original holes, hence the additional one.
I don,t know if your involved on this one Ilan but it,s just what I,ve been looking for for my project. Let me know if it could be available. Thanks.
