Excellent pics. DKG! I must make it a point to view this collection in person, being a hyderabadi myself!
A request- could you later please post the exact date and timings (if any) the collection would be opened to public view?
BTW, were the packard and buick originally hyderabad cars? Because APY is an early 60s regn., preceeded by APX (which was originally HYX, pre-AP formation?)
Or, as is the case with most Royal family cars (or also maybe due to the fact that the Nizam initially wasnt too happy about Hyderabad being included in AP), they were most likely 'officially' registered much later.
