Here's a link to the only site I've come across with decent walkaround-type photos of the P.11:
Inside Views of PZL P.11
The photos appear rather small on the page and there are no links to larger images, but you can view them full-size (which is still kinda small, but better than nuthin'!) by copying the URL of each photo and pasting it in your browser search bar. Or, you can just save them to your PC and they'll be full size when you view them.
There's several sites out there which either are devoted to or which have coverage of the PAF in WWII, but few have any information that's truly helpful to the modeler.
