This consignment shop used to get 2 or 3 H scarves a year... all from the same lady, an elderly woman who apparently has (had???) quite a collection! But they haven't had any in over a year, so either that lady is no longer consigning scarves, or... alas... she is no longer with us and her scarf collection has passed on to her heirs (hopefully scarf-lovers!).
She must have shared your excellent taste! What ever the reason for selling (or indeed stopping) I think she would be delighted to know that you're looking after them and enjoying them so much.
