This particular Grumman Mallard probably was built 58 years ago.
It was originally built with a pair of air-cooled piston radial engines.
Many older piston airplanes have been converted to turboprop
power under a specific Supplemental Type Certificate (STC)
issued by the FAA after the person/company doing the change
has turned in all engineering, manufacturing, ground test and flight
test data, then demonstrated the finished product in flight to the FAA.
Similar STC's have been issued for aircraft such as the venerable
DC-3, Beech 18, Bell H-13 helicopter (turboshaft engine instead of
turboprop engine), Ryan Navion and a bunch of others.
Getting an STC approved and issued by the FAA is almost as
complicated as designing a new airplane and getting it Type
Certificated by the FAA.

Subject: [MV] Seaplane crash off Miami?
They said this was a seaplane, I was wondering when
they quit building them, they said it was a Grumman
Turbine Mallard so I thought they must have built them
recently with turbine engines.
But NO! Today the news pukes said the plane was 58
years OLD!!
Is this an HMV? From the '30's?
