Excuse for writing in (poor) English. I look forward to an answer from our friend Ahala, too.
Some time ago I found these two pictures on the internet. I think they were official pictures from the British Museum, but I'm not able any loger to retrieve that web page.
Anyway, the "fishbone" is the same wich Ahala publishes (http://www.flickr.co...ome/5142654991/) and its actually an ingot of the BM, whilst the "club" ingot is reproduced in a drawing (http://www.letarot.it/page.aspx?id=283) referred to the BM.
I'm intrested now in the "club" ingot.
Is it the reverse side of the "fishbone"?
Wich is its Tulow and Vecchi classification (I'm sorry, I don't have the book)?
Is it the aes signatum known as "pole" ("asta") type? If not, wich is a picture of the "pole" variety?
