yes i've seen these in the museum and seem to recollect there was a note from the donor with them describing them as spindle whorls- which i pointed out at the time was a mistake-
however, little notice was taken...

if they were used as spindle whorls they would not have worked properly because the holes are large and not very regular so some would have spun lopsided.

the ones i got last year were dangling from a strip of embroidery that may have been designed to include them- which i showed here a while back, -they are much more likely to display how they were often used- and included in sets of 4 to weigh down the corners of small tablecloths...
