Very rare original FRAZER NASH BMW Enamel badge - 60mm Diameter - Probably from a Pre-war 319 326 327 328 Car ?

Very few pre-war BMW cars were imported into the UK in the 1930's badged as FN BMW's. 

This is from my garage clear out. I think I bought it at the Essen Classic car show years ago, but it's not from the pre-war BMW car I previously owned as that was not a FN car. 

Please check the photos and you will see there is some damage to the black enamel between the F and R and the S and H. I think this could be repaired by a professional enameller by adding new black glass and reheating. 

Low auction start price, but happy to consider sensible offers. 

Thanks for looking.
