1915 RFC manual - Silhouettes of Aeroplanes

[Allegra]

Found this on eBay a little while ago and 'won' it earlier today. Signed and dated 1916 - though the signature is somewhat illegible from the photos. The actual manual is dated 1915. I will post better pictures when it arrives - hopefully by the end of the month...... I trust that the sellers pictures do not come out too small.

Cheers
Tim
