I thought some of you chaps might find this of interest
Here is a link to all RAF Albert (K) Serials. Thats 48 airframes XV172 to XV223 and 18 airframes XV290 to XV307 ... ALL 66 !
The information is reasonably up to date in terms of "whereabouts" ... where you will see that some of the old "girls" are still happily flying
UK Serials and click the "XV" Range
Note also that there is an example photo for every airframe listed with the exception of of XV180 ... just 'click" the Serial No for the image.
