Type 19 Tiger and Rose Badge.
This badge has a makers mark with the letters ‘FN B’HAM which is short for F Narborough of Birmingham and is the same as a previous FN marked badge. This example shows the small round sweat hole behind the Coronet which, on most F Narborough badges, is usually obscured by solder.
This particular example is unusual in that it is an unfinished example that has not been correctly stamped out. It has areas to the front, rear and below the Tiger that should be voided but have been left solid.
