Boxed Silver Infantry Assault Badge. Type Petz & Lorenz.

Nickel silver based and in an excellent, unworn condition with all of the silver plate still present, the swastika and high points burnished. The swastika arms cut out.
Not marked but a known variation that has been attributed to the company of Petz & Lorenz from Unterreichenbach. With the typical „Lily pad“ type hinge. See GCA database.
The sales or storage box in a very good, slightly used condition.
Excellent example of this difficult to find early badge.
