Tiptaft maker, another one !

[Vincent]

Here I post another tiptaft Australian Commonwaelth Military Forces I found in 2009 with a mix of cap badge, see "mix of cap badges" in all albums to see the badges which were found together.
Badges seems to come from Ieper's area, Belgium. The seller was unable to tell me where exactly badges comes from but all seems to stay a long time at the same place. I was lucky to buy this whole of badges and I wanted to share this discover, more and more difficult to find...
My questions are :
- why is there twice the same maker's name on back of the badge ?
- are the Tiptaft badges so rare and expensive ?
Thanks for the answers gentlemen !
