Here's how I meant, besides the fact (as i mentioned) how the wire is laid out ....
Also, vacor has made a lot of strands with this light blue base ....
In addition to how the yarn is structured, look at this in the fourth photo (op) and see how it fades?
Typical in many vacors.
In veligs the thread is always quite clean, clean, as well as being twisted differently
Many, if not most wirepulls have several bubbles or just one and this sometimes very large.
In this case, it is not the big bubble that makes me exclude veiligglas but rather the structure of the thread itself
