Yet another question this time about a bonnet badge

[Steve Phillips]

As the title says another question I'm afraid,

Although I've said bonnet badge I'm actually refering to the circular badge on the slam panel just in front of the bonnet.

The badge is brass and shows no clear sign of previous plating,
But being as it's over 60 years old I don't know if it would have been plated with something like nickel or chrome or were they just left as brass.

If it was plated originally I can get it re plated but would prefer to keep it's appearance original and correct.

Many thanks

Steve
