Vacheron Constantin

Dear VC Community, This is my 1st post here at the VC forum and I am already asking for help. I acquired this vintage VC with tear drop lugs but I am not able to find any information on it. I have not seen any other vintage VC with Tear Drop Lugs in this ...  

Don't overlook the mushroom crown. Maybe more unusual than the tear drop lugs.

Maybe this may help :

teardrop lugs are such an iconic part of V&C designs
