1950's Archive Part 6: First RAF Chipmunks

This set of Chipmunk photos seems to show the very first airframes delivered to RAF training units. All taken at Cambridge in 1950, they were entering service with Cambridge UAS (RUC-codes) and 22RFS (RCU- codes).
Perhaps a Chipmunk specialist could confirm that WB562 was the first in service?

Photos as usual taken by the late Gerald Lawrence, digitised and made available by Tony Clarke.
