I think its a marinised Cummins 6bt 5.9 ltr in which case its an excellent engine.

My Cummins are badged as Thornycroft T358. I suspect the A may mean after cooled, e.g. 6BTA5.9M.
The base Cummins units may have some variations from the Thonrycroft marination. Thornycroft were renowned for the quality of the marinising parts they used.
A bus engine of similar vintage would likely have covered over a million miles by now, so to find some with just 50 hours will barely be broken in.
As Ben has said excellent engines, and also one of the commonest medium size diesels ever made - Buses, construction machinery, Dodge trucks, all used the Cummins 6BT block. They later formed the base engine of the Cummins QSB series.

Thanks for the input
They are indeed Cummins 6BTA 5.9L base engines with Bowman marinisation parts by the look of them
Thx

I had a pair of T358 engines which were Cummins 6BT, marinised by Thornycroft, in an Aquastar that I owned for a number of years without any significant engine issues.
