Will a Viscount ever fly again?

[avionic type]

Flyer joe we don't run the engines anymore for 3 reasons 1st the a/c has been with us for nearly 17 years and we cannot find out the internal state of the engines because the Tyne has no method whereby we can Boroscope it,and we decided it prudent not to run them again, 2nd the starter motor on 1 engine is U/S and we have no spares and 3 , the Bus museum is behind 1and 2engines and as it has plastc walls we think perhaps about 400 degrees C exhaust from the jet pipes might melt it
Pity it was fun to get the engines up to High Ground Idle and smell the old parrafin fumes again. I was normally on the ground engineers headset
