Are you speaking specifically about the 'Serjeant Webbs paper models'? Woof! 
Yep! Maybe I should try and contact the guy to make sure the models are more easily accessible.

All the tiny bits of paper on my cutting mat have become...
The Royal Navy Syrtis Major Squadron in 1889:-

The Aphid class aerial gunboats
Aphid,
Sandflea,
Wasp and
HornetDauntless and
Daring of the Dauntless class.
And in front the heavy units -
Reliant,
Thunderer and
Triumph.
This photograph was taken shortly after another Aphid -
Firefly - had been destroyed in the opening action of the Oenotrian war when she was immobilised by a lob gun impact and rammed by Hullcutter screw galleys.
(The British had also previously lost the Aphid class
Ladybird in action against the Fenian Ram in 1887 and the Dauntless class
Daring to the German
Hamburg Luftkreuzer during the So-Called "Mylarkt Incident" of 1886.)

As I say, I think these are fab.
The models require a certain amount of fettling - some of the glueing tags need to be trimmed to fit and notches in fins enlarged. Don't be afraid to use superglue on some of the more fiddly bits. For instance with the propellor struts on the larger flyers to chop off the glue tags entirely and use superglue on card edges instead.
And the page of British Bases appears to be oversized. These were printed at 94.12% to make them the same size as the others.
But, I mean, these have got to be the best Sky Galleons of Mars minis currently available.
