Astro compass
Hi all. Found in my late fathers possessions an Astro compass mk2. Not sure how as he got it as he worked in Brize in TCW. I am trying to find some history of it’s use. It has some white pen under the bubble housing. WF380 TF/NU 21 2 69. So any history on that aircraft would be good and what the other letters and date mean. The compass itself is a MK2A ref 6B/399 serial no 657. Also white markings KHI-R-I0-63 not sure what these mean. Would like to try and trace its origins. Any advice for further research would be much appreciated.
