Chain drive? I dont think so. Contra props were no novelty in 1949,It had a reduction gearbox gearbox. As for the distinctive sound , yes contra props with the Griffon or the turbine would have been distinctive.

Loyalties apart (I flew the AEW3, AS4 and T5 Gannets in the 60's) I think the AS and T5 were better lookers. NOBODY could accuse the AEW3 of being a good looker, but it was endearing and a pleasure to fly. Re. the chain drive, I am astounded!

The designations of this type is very confusing. The first protype was designated B-54 and YA5. This had the RR Griffin engine as did the second prototype also known as the YA7 but retaining the B-54 designation. The third protype with the Double Mambas was designated both the B-88 and YB1.

At least it looks nicer than the Gannet.

If I remember this aircraft had a chain drive to the propellers and it made an extraordinary noise when flying. One flew over our school playing fields at Uppingham, Rutland in the early 1950's and I always remember the sound.

Do you have any comments about this aircraft ?
