A few pigeon related items for your flying rats (click on the links):

Airfix Old Bill pigeon loft bus conversions

This one's particularly good

They're 1/32 but 1/35 scale buses are available from MiniArt... or this one

...or you could go the expensive route

Or just have a pigeon basket
...or two

Someone could try this interesting self propelled mobile pigeon deployment unit
(note that this utilises the basket above)

Next week... the bunnies

How original are these and I know from working on my mate's stall at shows, those 'Mantis' animal sets are always in huge demand and sell incredibly well and I have no reason to doubt these will be any different. I think this choice of release is quite inspired and they will sell crate loads.

Well I'm using the Airfix 1/32 bus BUT I'm going with these birds even it they may be a bit small.
