Vickers Varsity astro compass
I found in my late fathers possessions an Astro compass. Not sure why as he was in TCW at Brize in the 70/s. A typical scavenger. It had some writing under the bubble housing. WF380 TF/NU 21,3,69. Any history of that plane and the meaning of abbreviations and date please. Trying to find out the compasses origins as well. Astro compass MK2A serial no 657 ref 6B/399 Other markings not sure of meaning are KHI-R-I0-63 any help or direction would be much appreciated. Thankyou
