We did have 56-0471 along with 56-0477 56-0479, 56-0480, 56-0482, 56-0486, 56-0488 (crashed on Sewart 1962 I see it burn) 56-0490, 56-0499. 56-0505. I know I messed some. We even had some 54's, 2 B's and 17 E's 61-2359 to 61-2366 & 62-1801 to 62-1804 62-1808 to 62-1812 All new from factory. We receive 471 in 1962 in the 4451st CCTS and it very soon after became the 4442nd CCTS. I worked on it out of the engine shop from 62 until I was asigned to the 314TH FMS in Nov of 65. 471 was assigned to us from a Sewart unit and most likely the 463rd. The 4442nd was changing some aircraft out about the time I departed so it could have been one of them
