In the library section of the Webarchive, several issues of
Polish magazine Modelarz are available as well. Unfortunately this collection is far from complete.
Modelarz is/was a general modelling magazine, and every issue contains drawings for ships, aircraft, rockets and vehicles
The issues are available for individual download in pdf format, and can also be downloaded in jpg/jp2 format. It's easy to convert jp2 files to jpg. For a translation of the text, see my explanation in my post about Modellbau Heute.
