Maybe we should say a bit more in reply to the doubting thomas's query.
Identifying examples of historic Turkmen weaving is not easy -- in fact it is quite difficult and our assessments are surely not 100%.
That said, RK must state we feel 99.9% sure when we make such a designation.
We do not know of any magic bullet indication(s), nor do we ever expect to find them.
Assigning the term historic to any Turkmen weaving can only be done after a careful analysis of all its components are studied structure, dyes, materials, design, proportions, etc.
Doing this requires much experience and analytic skill.
Therefore, it surely is possible for a Tekke engsi, which is not historic, to have a potent spinning flower amulet elem. However, the corollary, one without a potent rendition of that amulet, is impossible.
By the way, not all historic Tekke engsi have this type of elem.
