Hello.
I had a look at two of those Mustang IV's (KM622 & KM631), some time ago:

The two pilots are buried at Ranchi, India. I suspect A-B has got the location wrong, possibly "Kangla", not "Kargulia".
The Tactical & Weapons Development Unit at Amarda Road, had three Mustang IV's on strength (KM147, KM174 & KM525).
Would welcome comments/opinions.
Col.
