Nice large photo, but unable to see the detail of the labels clearly...
Can you read the top label and tell me what it say after "By Appiontment..."
Also on the bottom label, it should have a notaion of the alcohol content/proof,
if you could provide that it would also be helpfull.
Most likely your bottle was produced between 1953-1960..but will know more whaen we can review the additional information.
