Hello, I am sure you will receive many replies. Have you considered
making your own?
You already have a book with many of the designs in it. Most of the
silver smiths I know proudly make their own using punches as a base.
Sand the head smooth, and carve/cut in a new design after heating the
metal, quench harden after that.
I believe the book you have has as to how to make your own.
Punches can be heavy when you order quite a few. I frequently see them
at shows, also in jewelry catalogs. Dan Woodward of Indian Jewelers
Supply is also on this board, and will probably reply to you. They are
a good source for many of these Indian related tools.
Good luck, Teresa
