This Nurtanio-built NBo105CB is a bit of an imposter. It was once registered as HH-1503 with the Indonesian air force and slated to become PK-DKJ, instead it went to the Indonesian Navy as spares source. In that capacity, it lingered at Juanda for years, marked PK-DKJ. Now, it has been revived as monument for the newly established museum at Surabaya's naval harbour. It received grey colours and serial "HE-4116" in the process, a serial never used in real service.
