Hello Anne,
What an interesting link you found. I'm sitting with Mum at the moment and we have a difference of opinion. She thinks it might be from the same maker, I'm still not sure how to tell lead and pewter apart. It weighs 20g, and is so soft, I can bend it with minimal pressure. I don't have any pewter to compare it to, but I do recall having pewter tankards years ago, and the metal seemed a little sturdier, although it did dent fairly easily.
The piece in the link was described as 1980's …..maybe it's a Past Times type of thing, a replica, although I'm not sure they would have used such an old fashioned pin/clasp.
Egyptian things were big in the 1920's. Foreign travel was on the increase as well, and I do think it looks quite souvenir-like.
Off to google "how to identify lead".
Will add to thread if I can find out anything else. Thanks, as always, Anne.
