I simply had to get this.
It might even be DOA and be a bitch to repair - I don't care.
It is only a signal tracer. But it is the cutest, most elaborate and versatile signal tracer that I have ever seen. It is a signal tracer to take on your XB-70 flight. Or beyond. A thing from a time when the U.S. were great - far beyond some utterings of contemporary figures. It was love on first sight.
Of course I could not tell this in advance. Now I have to live with the fear that one or more of you will know the thing, and describe how they once owned it until it drove them crazy and they smashed it or whatever. In that, rather unlikely case, I would refit insted of repair. But I do not think that this is the case. It looks right, so it should test right.
Thanks to the valiant Worsthorse for making it possible.
