For what it is worth, I agree with Sue about the similarities being likely significant. The odd shape of the online tail looks a bit polished, undulating... possibly repaired??... the look of it makes me worry it may have been longer in any case.... especially when looked at in comparison to your example. Just where damage may occur on this piece...
Now you have a likely factory name, it should be easier to find more of these cats from Ekenas, with long or short tails (!) and so further confirm it. Well done Anita, attributions can be a very long road.... you seem to be very near the end of this particular one!!
