The editor of these pages quarantees that none of  the plans or drawings shown on this site has never before been presented in any public media. 

Most of these images have originally been drawn with a carpenter pencil on an empty cigarrette box and the editor of these pages has later-on  scanned them.

Should somebody anyhow  have some claims about his copyrigths,  he is strongly advised to point them directly to the editor of these pages.
