Sorry, but this is going a little off topic now.

What a familiar name … being a modelist, his Spitfire marked “NK-K” is quite ubiquitous, even myself having a 1/18th scale example on the shelf.
Apart from that I never thought about A S C Lumsden. Actually I did not even think I would read his name again. Is there a biography behind that name? A quick google-search revealed nothing useful…

Try a Google search on “Alec Lumsden”.
